Facebook Detectron2 Mask-RCNN 安装踩坑

使用FaceBook官方github repo(网址)，按照官方教程一步一步来，有几个地方有问题，记录一下,蓝色是官方命令，红色是修改的命令

# first, make sure that your conda is setup properly with the right environment
# for that, check that `which conda`, `which pip` and `which python` points to the
# right path. From a clean conda env, this is what you need to do

conda create --name maskrcnn_benchmark -y
conda activate maskrcnn_benchmark

# this installs the right pip and dependencies for the fresh python
conda install ipython pip

# maskrcnn_benchmark and coco api dependencies
pip install ninja yacs cython matplotlib tqdm opencv-python

# follow PyTorch installation in https://pytorch.org/get-started/locally/
# we give the instructions for CUDA 9.0
conda install -c pytorch pytorch-nightly torchvision cudatoolkit=9.0

conda install pytorch torchvision cudatoolkit=10.2 -c pytorch-nightly

export INSTALL_DIR=$PWD

# install pycocotools
cd $INSTALL_DIR

# the following will install the lib with
# symbolic links, so that you can modify
# the files if you want and won't need to
# re-build it
python setup.py build develop


unset INSTALL_DIR
