+## Getting Started with Detectron2
+
+This document provides a brief intro of the usage of builtin command-line tools in detectron2.
+
+For a tutorial that involves actual coding with the API,
+see our [Colab Notebook](https://colab.research.google.com/drive/16jcaJoc6bCFAQ96jDe2HwtXj7BMD_-m5)
+which covers how to run inference with an
+existing model, and how to train a builtin model on a custom dataset.
+
+
+### Inference Demo with Pre-trained Models
+
+1. Pick a model and its config file from
+  [model zoo](MODEL_ZOO.md),
+  for example, `mask_rcnn_R_50_FPN_3x.yaml`.
+2. We provide `demo.py` that is able to demo builtin configs. Run it with:
+```
+cd demo/
+python demo.py --config-file ../configs/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x.yaml \
+  --input input1.jpg input2.jpg \
+  [--other-options]
+  --opts MODEL.WEIGHTS detectron2://COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x/137849600/model_final_f10217.pkl
+```
+The configs are made for training, therefore we need to specify `MODEL.WEIGHTS` to a model from model zoo for evaluation.
+This command will run the inference and show visualizations in an OpenCV window.
+
+For details of the command line arguments, see `demo.py -h` or look at its source code
+to understand its behavior. Some common arguments are:
+* To run __on your webcam__, replace `--input files` with `--webcam`.
+* To run __on a video__, replace `--input files` with `--video-input video.mp4`.
+* To run __on cpu__, add `MODEL.DEVICE cpu` after `--opts`.
+* To save outputs to a directory (for images) or a file (for webcam or video), use `--output`.
+
+
+### Training & Evaluation in Command Line
+
+We provide two scripts in "tools/plain_train_net.py" and "tools/train_net.py",
+that are made to train all the configs provided in detectron2. You may want to
+use it as a reference to write your own training script.
+
+Compared to "train_net.py", "plain_train_net.py" supports fewer default
+features. It also includes fewer abstraction, therefore is easier to add custom
+logic.
+
+To train a model with "train_net.py", first
+setup the corresponding datasets following
+[datasets/README.md](./datasets/README.md),
+then run:
+```
+cd tools/
+./train_net.py --num-gpus 8 \
+  --config-file ../configs/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_1x.yaml
+```
+
+The configs are made for 8-GPU training.
+To train on 1 GPU, you may need to [change some parameters](https://arxiv.org/abs/1706.02677), e.g.:
+```
+./train_net.py \
+  --config-file ../configs/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_1x.yaml \
+  --num-gpus 1 SOLVER.IMS_PER_BATCH 2 SOLVER.BASE_LR 0.0025
+```
+
+To evaluate a model's performance, use
+```
+./train_net.py \
+  --config-file ../configs/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_1x.yaml \
+  --eval-only MODEL.WEIGHTS /path/to/checkpoint_file
+```
+For more options, see `./train_net.py -h`.
+
+### Use Detectron2 APIs in Your Code
+
+See our [Colab Notebook](https://colab.research.google.com/drive/16jcaJoc6bCFAQ96jDe2HwtXj7BMD_-m5)
+to learn how to use detectron2 APIs to:
+1. run inference with an existing model
+2. train a builtin model on a custom dataset
+
+See [detectron2/projects](https://github.com/facebookresearch/detectron2/tree/main/projects)
+for more ways to build your project on detectron2.

+## Installation
+
+### Requirements
+- Linux or macOS with Python ≥ 3.6
+- PyTorch ≥ 1.8 and [torchvision](https://github.com/pytorch/vision/) that matches the PyTorch installation.
+  Install them together at [pytorch.org](https://pytorch.org) to make sure of this
+- OpenCV is optional but needed by demo and visualization
+
+
+### Build Detectron2 from Source
+
+gcc & g++ ≥ 5.4 are required. [ninja](https://ninja-build.org/) is optional but recommended for faster build.
+After having them, run:
+```
+python -m pip install 'git+https://github.com/facebookresearch/detectron2.git'
+# (add --user if you don't have permission)
+
+# Or, to install it from a local clone:
+git clone https://github.com/facebookresearch/detectron2.git
+python -m pip install -e detectron2
+
+# On macOS, you may need to prepend the above commands with a few environment variables:
+CC=clang CXX=clang++ ARCHFLAGS="-arch x86_64" python -m pip install ...
+```
+
+To __rebuild__ detectron2 that's built from a local clone, use `rm -rf build/ **/*.so` to clean the
+old build first. You often need to rebuild detectron2 after reinstalling PyTorch.

+### Common Installation Issues
+
+Click each issue for its solutions:
+
+<details>
+<summary>
+Undefined symbols that looks like "TH..","at::Tensor...","torch..."
+</summary>
+<br/>
+
+This usually happens when detectron2 or torchvision is not
+compiled with the version of PyTorch you're running.
+
+If the error comes from a pre-built torchvision, uninstall torchvision and pytorch and reinstall them
+following [pytorch.org](http://pytorch.org). So the versions will match.
+
+If the error comes from a pre-built detectron2, check [release notes](https://github.com/facebookresearch/detectron2/releases),
+uninstall and reinstall the correct pre-built detectron2 that matches pytorch version.
+
+If the error comes from detectron2 or torchvision that you built manually from source,
+remove files you built (`build/`, `**/*.so`) and rebuild it so it can pick up the version of pytorch currently in your environment.
+
+If the above instructions do not resolve this problem, please provide an environment (e.g. a dockerfile) that can reproduce the issue.

+
+<details>
+<summary>
+Missing torch dynamic libraries, OR segmentation fault immediately when using detectron2.
+</summary>
+This usually happens when detectron2 or torchvision is not
+compiled with the version of PyTorch you're running. See the previous common issue for the solution.
+</details>
+
+<details>
+<summary>
+Undefined C++ symbols (e.g. "GLIBCXX..") or C++ symbols not found.
+</summary>
+<br/>
+Usually it's because the library is compiled with a newer C++ compiler but run with an old C++ runtime.
+
+This often happens with old anaconda.
+It may help to run `conda update libgcc` to upgrade its runtime.
+
+The fundamental solution is to avoid the mismatch, either by compiling using older version of C++
+compiler, or run the code with proper C++ runtime.
+To run the code with a specific C++ runtime, you can use environment variable `LD_PRELOAD=/path/to/libstdc++.so`.
+
+</details>
+
+<details>
+<summary>
+"nvcc not found" or "Not compiled with GPU support" or "Detectron2 CUDA Compiler: not available".
+</summary>
+<br/>
+CUDA is not found when building detectron2.
+You should make sure
+
+```
+python -c 'import torch; from torch.utils.cpp_extension import CUDA_HOME; print(torch.cuda.is_available(), CUDA_HOME)'
+```
+
+print `(True, a directory with cuda)` at the time you build detectron2.
+
+Most models can run inference (but not training) without GPU support. To use CPUs, set `MODEL.DEVICE='cpu'` in the config.
+</details>
+
+<details>
+<summary>
+"invalid device function" or "no kernel image is available for execution".
+</summary>
+<br/>
+Two possibilities:
+
+* You build detectron2 with one version of CUDA but run it with a different version.
+
+  To check whether it is the case,
+  use `python -m detectron2.utils.collect_env` to find out inconsistent CUDA versions.
+  In the output of this command, you should expect "Detectron2 CUDA Compiler", "CUDA_HOME", "PyTorch built with - CUDA"
+  to contain cuda libraries of the same version.
+
+  When they are inconsistent,
+  you need to either install a different build of PyTorch (or build by yourself)
+  to match your local CUDA installation, or install a different version of CUDA to match PyTorch.
+
+* PyTorch/torchvision/Detectron2 is not built for the correct GPU SM architecture (aka. compute capability).
+
+  The architecture included by PyTorch/detectron2/torchvision is available in the "architecture flags" in
+  `python -m detectron2.utils.collect_env`. It must include
+  the architecture of your GPU, which can be found at [developer.nvidia.com/cuda-gpus](https://developer.nvidia.com/cuda-gpus).
+
+  If you're using pre-built PyTorch/detectron2/torchvision, they have included support for most popular GPUs already.
+  If not supported, you need to build them from source.
+
+  When building detectron2/torchvision from source, they detect the GPU device and build for only the device.
+  This means the compiled code may not work on a different GPU device.
+  To recompile them for the correct architecture, remove all installed/compiled files,
+  and rebuild them with the `TORCH_CUDA_ARCH_LIST` environment variable set properly.
+  For example, `export TORCH_CUDA_ARCH_LIST="6.0;7.0"` makes it compile for both P100s and V100s.

+<summary>
+Undefined CUDA symbols; Cannot open libcudart.so
+</summary>
+<br/>
+The version of NVCC you use to build detectron2 or torchvision does
+not match the version of CUDA you are running with.
+This often happens when using anaconda's CUDA runtime.
+
+Use `python -m detectron2.utils.collect_env` to find out inconsistent CUDA versions.
+In the output of this command, you should expect "Detectron2 CUDA Compiler", "CUDA_HOME", "PyTorch built with - CUDA"
+to contain cuda libraries of the same version.
+
+When they are inconsistent,
+you need to either install a different build of PyTorch (or build by yourself)
+to match your local CUDA installation, or install a different version of CUDA to match PyTorch.

+
+
+<details>
+<summary>
+C++ compilation errors from NVCC / NVRTC, or "Unsupported gpu architecture"
+</summary>
+<br/>
+A few possibilities:
+
+1. Local CUDA/NVCC version has to match the CUDA version of your PyTorch. Both can be found in `python collect_env.py`
+   (download from [here](./detectron2/utils/collect_env.py)).
+   When they are inconsistent, you need to either install a different build of PyTorch (or build by yourself)
+   to match your local CUDA installation, or install a different version of CUDA to match PyTorch.
+
+2. Local CUDA/NVCC version shall support the SM architecture (a.k.a. compute capability) of your GPU.
+   The capability of your GPU can be found at [developer.nvidia.com/cuda-gpus](https://developer.nvidia.com/cuda-gpus).
+   The capability supported by NVCC is listed at [here](https://gist.github.com/ax3l/9489132).
+   If your NVCC version is too old, this can be workaround by setting environment variable
+   `TORCH_CUDA_ARCH_LIST` to a lower, supported capability.
+
+3. The combination of NVCC and GCC you use is incompatible. You need to change one of their versions.
+   See [here](https://gist.github.com/ax3l/9489132) for some valid combinations.
+   Notably, CUDA<=10.1.105 doesn't support GCC>7.3.
+
+   The CUDA/GCC version used by PyTorch can be found by `print(torch.__config__.show())`.

+# Detectron2 Model Zoo and Baselines
+
+## Introduction
+
+This file documents a large collection of baselines trained
+with detectron2 in Sep-Oct, 2019.
+All numbers were obtained on [Big Basin](https://engineering.fb.com/data-center-engineering/introducing-big-basin-our-next-generation-ai-hardware/)
+servers with 8 NVIDIA V100 GPUs & NVLink. The speed numbers are periodically updated with latest PyTorch/CUDA/cuDNN versions.
+You can access these models from code using [detectron2.model_zoo](https://detectron2.readthedocs.io/modules/model_zoo.html) APIs.
+
+In addition to these official baseline models, you can find more models in [projects/](projects/).
+
+#### How to Read the Tables
+* The "Name" column contains a link to the config file. Models can be reproduced using `tools/train_net.py` with the corresponding yaml config file,
+  or `tools/lazyconfig_train_net.py` for python config files.
+* Training speed is averaged across the entire training.
+  We keep updating the speed with latest version of detectron2/pytorch/etc.,
+  so they might be different from the `metrics` file.
+  Training speed for multi-machine jobs is not provided.
+* Inference speed is measured by `tools/train_net.py --eval-only`, or [inference_on_dataset()](https://detectron2.readthedocs.io/modules/evaluation.html#detectron2.evaluation.inference_on_dataset),
+  with batch size 1 in detectron2 directly.
+  Measuring it with custom code may introduce other overhead.
+  Actual deployment in production should in general be faster than the given inference
+  speed due to more optimizations.
+* The *model id* column is provided for ease of reference.
+  To check downloaded file integrity, any model on this page contains its md5 prefix in its file name.
+* Training curves and other statistics can be found in `metrics` for each model.
+
+#### Common Settings for COCO Models
+* All COCO models were trained on `train2017` and evaluated on `val2017`.
+* The default settings are __not directly comparable__ with Detectron's standard settings.
+  For example, our default training data augmentation uses scale jittering in addition to horizontal flipping.
+
+  To make fair comparisons with Detectron's settings, see
+  [Detectron1-Comparisons](configs/Detectron1-Comparisons/) for accuracy comparison,
+  and [benchmarks](https://detectron2.readthedocs.io/notes/benchmarks.html)
+  for speed comparison.
+* For Faster/Mask R-CNN, we provide baselines based on __3 different backbone combinations__:
+  * __FPN__: Use a ResNet+FPN backbone with standard conv and FC heads for mask and box prediction,
+    respectively. It obtains the best
+    speed/accuracy tradeoff, but the other two are still useful for research.
+  * __C4__: Use a ResNet conv4 backbone with conv5 head. The original baseline in the Faster R-CNN paper.
+  * __DC5__ (Dilated-C5): Use a ResNet conv5 backbone with dilations in conv5, and standard conv and FC heads
+    for mask and box prediction, respectively.
+    This is used by the Deformable ConvNet paper.
+* Most models are trained with the 3x schedule (~37 COCO epochs).
+  Although 1x models are heavily under-trained, we provide some ResNet-50 models with the 1x (~12 COCO epochs)
+  training schedule for comparison when doing quick research iteration.
+
+#### ImageNet Pretrained Models
+
+It's common to initialize from backbone models pre-trained on ImageNet classification tasks. The following backbone models are available:
+
+* [R-50.pkl](https://dl.fbaipublicfiles.com/detectron2/ImageNetPretrained/MSRA/R-50.pkl): converted copy of [MSRA's original ResNet-50](https://github.com/KaimingHe/deep-residual-networks) model.
+* [R-101.pkl](https://dl.fbaipublicfiles.com/detectron2/ImageNetPretrained/MSRA/R-101.pkl): converted copy of [MSRA's original ResNet-101](https://github.com/KaimingHe/deep-residual-networks) model.
+* [X-101-32x8d.pkl](https://dl.fbaipublicfiles.com/detectron2/ImageNetPretrained/FAIR/X-101-32x8d.pkl): ResNeXt-101-32x8d model trained with Caffe2 at FB.
+* [R-50.pkl (torchvision)](https://dl.fbaipublicfiles.com/detectron2/ImageNetPretrained/torchvision/R-50.pkl): converted copy of [torchvision's ResNet-50](https://pytorch.org/docs/stable/torchvision/models.html#torchvision.models.resnet50) model.
+  More details can be found in [the conversion script](tools/convert-torchvision-to-d2.py).
+
+Note that the above models have __different__ format from those provided in Detectron: we do not fuse BatchNorm into an affine layer.
+Pretrained models in Detectron's format can still be used. For example:
+* [X-152-32x8d-IN5k.pkl](https://dl.fbaipublicfiles.com/detectron/ImageNetPretrained/25093814/X-152-32x8d-IN5k.pkl):
+  ResNeXt-152-32x8d model trained on ImageNet-5k with Caffe2 at FB (see ResNeXt paper for details on ImageNet-5k).
+* [R-50-GN.pkl](https://dl.fbaipublicfiles.com/detectron/ImageNetPretrained/47261647/R-50-GN.pkl):
+  ResNet-50 with Group Normalization.
+* [R-101-GN.pkl](https://dl.fbaipublicfiles.com/detectron/ImageNetPretrained/47592356/R-101-GN.pkl):
+  ResNet-101 with Group Normalization.
+
+These models require slightly different settings regarding normalization and architecture. See the model zoo configs for reference.

+#### New baselines using Large-Scale Jitter and Longer Training Schedule
+
+The following baselines of COCO Instance Segmentation with Mask R-CNN are generated
+using a longer training schedule and large-scale jitter as described in Google's
+[Simple Copy-Paste Data Augmentation](https://arxiv.org/pdf/2012.07177.pdf) paper. These
+models are trained from scratch using random initialization. These baselines exceed the
+previous Mask R-CNN baselines.
+
+In the following table, one epoch consists of training on 118000 COCO images.

+Backward compatibility of configs.

+Instructions to bump version:
++ It's not needed to bump version if new keys are added.
+  It's only needed when backward-incompatible changes happen
+  (i.e., some existing keys disappear, or the meaning of a key changes)
++ To bump version, do the following:
+    1. Increment _C.VERSION in defaults.py
+    2. Add a converter in this file.
+
+      Each ConverterVX has a function "upgrade" which in-place upgrades config from X-1 to X,
+      and a function "downgrade" which in-place downgrades config from X to X-1
+
+      In each function, VERSION is left unchanged.
+
+      Each converter assumes that its input has the relevant keys
+      (i.e., the input is not a partial config).
+    3. Run the tests (test_config.py) to make sure the upgrade & downgrade
+       functions are consistent.
