[BUG] inconsistent dependency on Pymanopt

[SimonYansenZhao]

Description

In setup.py, pymanopt is required as a dependent package:

extras_require["experimental"] = [
    # xlearn requires cmake to be pre-installed
    "xlearn==0.40a1",
    # VW C++ binary needs to be installed manually for some code to work
    "vowpalwabbit>=8.9.0,<9",
    # nni needs to be upgraded
    "nni==1.5",
    "pymanopt>=0.2.5",
]

However, in tests/ci/azureml_tests/submit_groupwise_azureml_pytest.py, pymanopt is replaced:

    conda_dep.add_pip_package(
        "pymanopt@https://github.com/pymanopt/pymanopt/archive/fb36a272cdeecb21992cfd9271eb82baafeb316d.zip"
    )

This inconsistency may cause problems in the future, and complicate testing.

In which platform does it happen?

This behavior only happens in testing.

How do we replicate the issue?

Triggering a test will make it happen.

Expected behavior (i.e. solution)

Testing should not change the dependencies of the recommenders package.

Some modules were renamed in the new version of Pymanopt, such as pymanopt.solvers. See https://github.com/pymanopt/pymanopt/issues/207
