[environment configuration]pwc-net

This paper is based on Source code github Of PyTorch/README.md Step configuration described in , meet bug solve bug

The environment create

conda create -n pwcnet_test python=2.7 anaconda	// python2.7 conda The environment create 
conda activate pwcnet_test													//  Get into python Environmental Science 

pytorch And other dependent Downloads

It has been configured once before, but torch0.2 Out of commission , download torch0.4

pip install torch==0.4.1 torchvision==0.2.2 -f https://download.pytorch.org/whl/torch_stable.html
pip install torchvision visdom dominate opencv-python cffi

install opencv-python You may make a mistake :

ERROR: Command errored out with exit status 1: /home/hongfeng/anaconda3/envs/pwcnet_test/bin/python /home/hongfeng/anaconda3/envs/pwcnet_test/lib/python2.7/site-packages/pip/_vendor/pep517/_in_process.py get_requires_for_build_wheel /tmp/tmpuP82ch Check the logs for full command output.
This is because python2.7 Installation is no longer supported opencv-python, You can download and install it yourself ：
① Go to Download address Find the corresponding version to download ;
② In the virtual environment, use the following command to install

pip install opencv_python-3.1.0.5-cp27-cp27mu-manylinux1_x86_64.whl

install cffi May report an error ：
raise TypeError, “dist must be a Distribution instance”
TypeError: dist must be a Distribution instance
Use the following command to install ：

pip install certifi --ignore-installed

install external packages

Finally, go to the corresponding folder and execute the following command

cd external_packages/correlation-pytorch-master/
bash make_cuda.sh
cd ../../

I have encountered a problem that has been bothering me for a long time ：
TypeError: dist must be a Distribution instance
Many solutions have been found on the Internet ：
I feel ： Maybe it is not installed cuda

②steuptool Version issue for （ and No solution My question ）
The solution is to replace the lower version of setuptools, Run the following command in the virtual environment

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-0.9.8.tar.gz
tar zxvf setuptools-0.9.8.tar.gz
cd setuptools-0.9.8/
sudo python setup.py install
cd
sudo easy_install pip
sudo aptitude install libffi-dev
git clone [email protected].com:openstack/swift.git
cd swift/
sudo python setup.py install

stay swift An error is reported when running the last line of command in ：
distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse(‘pbr’)
This simple pip install pbr that will do , originate github issue

pytorch Version doesn't work , I gave up my friends
