ModuleNotFoundError: No module named 'sklearn' python

Question

For some reason my Python (Spyder) is not recognising sklearn library and pyodbc library

2 weeks ago everything was ok,

but not sure what happened that I am getting this error

ModuleNotFoundError: No module named 'sklearn'

and

ModuleNotFoundError: No module named 'pyodbc'

When I try

pip install sklearn

I get

pip install sklearn
Note: you may need to restart the kernel to use updated packages.
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

I restarted my computer still the same !

Any idea how to fix this?

Edit

When I try to pip install it from Anaconda Poweshell Promopt

(base) PS C:\Users\ASMGX> conda install sklearn
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

to uninstall Anaconda and Python and re-install them again!
