Error building from source on macOS

fepegar commented 4 years ago

🐛 Bug

I can't build torchvision from source. I get the following error in the log:

/private/tmp/vision/torchvision/csrc/cpu/decoder/util.cpp:258:26: error: implicit instantiation of undefined template 'std::__1::array<char, 1024>'
  std::array<char, 1024> buffer;

To Reproduce

Steps to reproduce the behavior:

$ conda create -n tv python -y && conda activate tv
$ git clone --depth 1 git@github.com:pytorch/vision.git
$ cd vision
$ MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py install

Output

Interestingly, was trying to replicate your error and got something completely different:

error

I'll take a look into this a bit later next week, but here is the workaround I found

conda create -n tv python -y && conda activate tv
conda install -c conda-forge av
conda install pytorch -c pytorch
git clone https://github.com/pytorch/vision.git
cd vision; git checkout tags/v0.6.0
$ MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py install

a few things of note @fepegar : I think it's crucial to install ffmpeg/pyav before trying to build TV from source. Try building pyav with conda install -c conda-forge av, and continue with the build as is. It worked for me in the end.

Maybe we should document the build process better? :)

Thanks @bjuncek,

I just tried the following commands with the same luck:

conda create -n tv python -y && conda activate tv
conda install -c conda-forge av -y
conda install pytorch -c pytorch -y
git clone https://github.com/pytorch/vision.git --depth 1
cd vision
MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py install

@fepegar thanks for opening this issue.

This should be fixed with https://github.com/pytorch/vision/pull/2224, can you pull it and give it a try?

fepegar commented 4 years ago

Silly question, but how do I pull your branch?

fmassa commented 4 years ago

It would be something like

git remote add fmassa git@github.com:fmassa/vision-1.git
git fetch fmassa
git checkout fix-missing-include-decoder

but I've just merged this on master, so you can just pull from torchvision again.

The issue got auto-closed due to the merge, but let me know if it doesn't compile for you

fepegar commented 4 years ago

Thanks. I ran the lines form https://github.com/pytorch/vision/issues/2220#issuecomment-629542543. Build seems OK.

Then I ran python -c "import torchvision; torchvision.set_video_backend('video_reader')" and got the error I mentioned in https://github.com/pytorch/vision/issues/2216#issuecomment-629258828.

fmassa commented 4 years ago

@fepegar this is a different issue, and I have a couple of ideas of what the problem might be:

you had some parts of the old torchvision that got compiled, and only recompiled the video_reader backend at a later attempt, where the pytorch version might have changed in between. If you could do python setup.py clean and then re-compile torchvision, this would let us know if that's indeed the case or not (my guess is that this should fix it)
something else is messing up with the torchscript (like virtualenv? although you seen to be using conda). We will be removing explicit torchscript annotations from torchvision very soon, so this will not show up at import time, although the issue might still be there hidden, which is that your compiled library is not picking the right files.

fepegar commented 4 years ago

clean didn't help. Also, I clone the repo every time I retry, so it should be clean at the beginning anyway.

I'll open a new issue.
