Installing requirements issues

Installing requirements issues:

1. on python 3.11:

   "ERROR: Ignored the following versions that require a different python version: 0.36.0 Requires-Python >=3.6,<3.10; 0.37.0 Requires-Python >=3.7,<3.10; 0.38.0 Requires-Python >=3.7,<3.11; 0.38.1 Requires-Python >=3.7,<3.11

2. on python 3.10:

   ERROR: Ignored the following versions that require a different python version: 0.36.0 Requires-Python >=3.6,<3.10; 0.37.0 Requires-Python >=3.7,<3.10

   ERROR: No matching distribution found for llvmlite==0.36.0
   

3. on python 3.9:

   ERROR: Cannot install -r requirements.txt (line 10), -r requirements.txt (line 11), -r requirements.txt (line 8) and torch==1.8.1 because these package versions have conflicting dependencies.
   
   The conflict is caused by:
       The user requested torch==1.8.1
       timm 0.4.5 depends on torch>=1.4
       torchaudio 0.8.1 depends on torch==1.8.1
       torchvision 0.10.0 depends on torch==1.9.0
   

4. I removed the specific versions of the packages and tried again with 3.11:

     error: subprocess-exited-with-error
   
     × Getting requirements to build wheel did not run successfully.
     │ exit code: 1
     ╰─> [15 lines of output]
         The 'sklearn' PyPI package is deprecated, use 'scikit-learn'
         rather than 'sklearn' for pip commands.
   
         Here is how to fix this error in the main use cases:
         - use 'pip install scikit-learn' rather than 'pip install sklearn'
         - replace 'sklearn' by 'scikit-learn' in your pip requirements files
    (requirements.txt, setup.py, setup.cfg, Pipfile, etc ...)
         - if the 'sklearn' package is used by one of your dependencies,
    it would be great if you take some time to track which package uses
    'sklearn' instead of 'scikit-learn' and report it to their issue tracker
         - as a last resort, set the environment variable
    SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True to avoid this error

         https://github.com/scikit-learn/sklearn-pypi-package

     note: This error originates from a subprocess, and is likely not a problem with pip.
   error: subprocess-exited-with-error
   

• Question1: Is it necessary to specify the library versions?
• Question2: is 'sklearn' library required while it has been deprecated?
• Question3: Can I use Python 3.11, or I should use earlier versions, i.e., 3.10, 3.9?
