poetry cannot install the latest torch version

Issue

Tried to add torch 1.4 with no success. It goes into some kind of infinite loop and never stops. It also seems to be downloading the wrong wheel and then just gets stuck.

poetry add torch --platform linux --python 3.8 -vvv

Tries to download the following wheel: PyPI: Downloading wheel: torch-1.4.0-cp27-cp27m-manylinux1_x86_64.whl and then gets stuck here.

The correct wheel would be torch-1.4.0-cp38-cp38-manylinux1_x86_64.whl

EDIT:
Simply trying to poetry add torch also leads to the same issue

The "Download wheel" log relates to a missing requires_dist in the pypi json data for the package, thereby causing poetry to fallback to downloading the first available wheel to introspect.

This will still lead to the correct version of the package being installed as the initial download is performed only for metadata parsing. See blow. Additionally, the delay is because the package torch is larger than your usual package on PyPI. Waiting for it to download will succeed. Once the cache is available there should no longer be a wait.

$ poetry add torch --platform linux --python "^3.7" -vvv

Closing this as this is not an issue. The situation will be improved via #2284 and #999.

@abn What If I want to keep torch dependency platform independent?
