Building Wheel files (why would it ask for the wrong version?)

[coreyhanson]

I've been getting some unexpected behavior when creating a wheel for a manual build of Pytorch. If I decide to just directly install it (using python 3.8), it works perfectly, but if I try to save those files to a wheel, and install from directly from that it suddenly decides that python 3.7 and under should be required.

This is bash code, but the problem is python based

# I'm doing it inside a custom conda environment
source activate $CONDA_ROOT
# Just a temp directory to save out the wheel to
mkdir /opt/conda/wheel-pytorch
git clone https://github.com/pytorch/pytorch.git
cd pytorch
git submodule sync && git submodule update --init --recursive
TORCH_CUDA_ARCH_LIST="3.5 5.2 6.0 6.1 7.0+PTX" TORCH_NVCC_FLAGS="-Xfatbin -compress-all" \
CMAKE_PREFIX_PATH="$(dirname $(which conda))/../" \
# If these last two lines are replaced with a simple "pip install -v" . , the install works
pip wheel . --wheel-dir=/opt/conda/wheel-pytorch
pip install --no-index --find-links=/opt/conda/wheel-pytorch -r requirements.txt

This is what happens when trying to run the above code. It breaks the Dockerfile that I'm creating it with (for the purpose of a non-bloated multistage build)

Error:
Looking in links: /opt/conda/wheel-pytorch
Ignoring dataclasses: markers 'python_version < "3.7"' don't match your environment
ERROR: Could not find a version that satisfies the requirement future
ERROR: No matching distribution found for future

I suspect that some of the dependencies might be responsible for asking for the wrong python version, but why would it break during an install using the wheel (with the same exact version) if it worked on the standard install.

Is there a way to force the wheel to behave as expected and respect the specs of the environment that built it?

Might have been a mindless oversight instead of a problem with the wheel package.

Testing a build to see if changing directories will fix the problem (looking at the wrong requirements.txt)

Will update thread in case it works.
