SHARK-1.0: Fixes to requirements for newer dependency versions

[one-lithe-rune]

Motivation

Setting up a venv for SHARK-1.0 was getting to be a right pain, due to #2095 and there apparently no longer being any common torch version that fits both torchvision and the version of torch-mlir we have pinned for SHARK-1.0.

Changes

• Adds mpmath==1.3.0 as a direct requirement to workaround a sympy dependency issue.
• Change setup_venv.ps1 to install torchvision --nodeps. This avoids a failure to find any common torch version dependency between the pinned torch-mlir version and torchvision after a long search. This also more closely matches what setup_venv.sh does.

Possible Problems/Concerns

• Still complains about the dependency conflict around torchvision, but at least it doesn't now check every listed version of torchvision at the index url before giving up.
• Shouldn't we just pip --freeze everything and pin it all for Shark-1.0,given the current dev effort is all on Studio2/Turbine?

Thanks, LGTM. I haven't been looking at 1.0 but I can't think of any reason not to pin everything.

I'm still getting some wonkiness around this area. On ./setup_venv.ps1 everything seems to run well except when it comes to pip install torchvision. There seems to be another version clashing. It downgrades torch 2.40. to torch 2.2.0.devxxxx. Error below.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. torch-mlir 20231210.1048 requires torch==2.2.0.dev20231204, but you have torch 2.4.0 which is incompatible.
