Installation error using pipenv + torchvision

pipenv, version 6.2.4

Attempting to install pytorch. Torch installation succeeded but when trying to install torchvision, I encountered the error below. Installation succeeds via pip3 with no virtualenv.

Error is:

Pipfile:

url = "https://pypi.python.org/simple"
verify_ssl = true

[packages]
torchvision = "*"

[packages.040d199]
file = "http://download.pytorch.org/whl/torch-0.2.0.post3-cp36-cp36m-macosx_10_7_x86_64.whl"

If anyone else stumbles across this, I was able to do:

pipenv run pip install --no-deps torchvision to proceed.

This workaround doesn’t update the Pipfile though right? So maybe the pipenv issue here is to have something like pipenv install --no-deps torchvision that will add torchvision to the Pipfile (and Pipfile.lock) with some special flag that says that dependencies are not to be installed. Another alternative is to install according to the order of the Pipfile and then in this case for example, one would make sure to put the pytorch wheel before the torchvision package

@kennethreitz - could you please comment regarding the above? What’s the correct way to deal with this? Thanks in advance!
