Why am I not able to check Python version with the command 'pe = pyenv'; pe.Version'?

I installed Python with supported version by referring the link.

https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/python-compatibility.pdf

I see empty return for Python version though I typed the 'pe = pyenv'; pe.Version' according to the following documentation.

Please set Python version with the full path of the location of python installation.

For example,

pyenv('Version','C:\Users\sji\AppData\Local\Programs\Python\Python38\python.exe')
