tensorflow looking for opt-einsum instead opt_einsum

[flomock]

Actual Behavior

pkg_resources.ContextualVersionConflict: (opt-einsum 0+untagged.56.g2664021.dirty (/home/go96bix/programs/conda/envs/vidhop_test/lib/python3.7/site-packages), Requirement.parse('opt-einsum>=2.3.2'), {'tensorflow'}) tensorflow 2.2.0 expects opt-einsum>=2.3.2 But the real name of the package is opt_einsum . There is a version falsely named 3.0.0, but this version only works with scipy 1.4.1 but your package installs version 1.5.

Expected Behavior

Fix the naming, I think then the environment solving works as expected.

Steps to Reproduce

conda install -c tensorflow

Anaconda or Miniconda version:

You look to have both opt-einsum and opt_einsum installed with different versions. The former is coming from conda-forge. If you create an environment using only packages from the anaconda or defaults channels does this problem persist?

[flomock]

Seams that only opt_einsum is installed, but then I get the error: pkg_resources.ContextualVersionConflict: (scipy 1.5.0 (/home/go96bix/programs/conda/envs/vidhop_test/lib/python3.7/site-packages), Requirement.parse('scipy==1.4.1; python_version >= "3"'), {'tensorflow'}) seems like one of my packages expects scipy 1.4.1 but that requirement has not been part of the environment requirements during installation. But I'm not sure where this requirement is coming from, maybe it's not from the tensorflow package.
