Hi
I am trying to implement vader sentiment scores. In my earlier thread, Walter Roberson has provided me a python implementation link. As far as I understand, I need to connect to the python program from my matlab. But I have no clue from where to begin. Besides, when did I execute this from my matlab it shows error.
>> pyenv('Version','version')
Undefined function or variable 'pyenv'.
I have python 3.7.4 installed(64 bit) and I already added the path in the matlab as well. Would you please guide me how to resolve the issue and how to connect to the python function.
thanks,

Hey Saugata,
you should follow this guide from mathworks: Undefined variable "py" or function "py.command"
It helps you to ensure you have installed and configured Python correctly.

pyenv function is introduced in R2019b version. Hence you are getting the error in R2019a version as:
>> pyenv('Version','version')
Undefined function or variable 'pyenv'.
You can use pyversion function for the same in R2019a version. This should return you the details regarding python version and interpreter.
