Stata and Python 3.13 virtual environment

[Janet Hill]

I have no problem using Stata 18IC with Python without an environment in Windows

. python query

    Python Settings
      set python_exec      C:\Python313\python.exe
      set python_userpath  

    Python system information
      initialized          no
      version              3.13.0
      architecture         64-bit
      library path         C:\Python313\python313.dll

. python:
----------------------------------------------- python (type end to exit) ------------------------------------------------------------------------------------------------------------------------
>>> a = 1
>>> b = 2
>>> c = a + b
>>> c
3
>>> end
----------------------------------------------------------

However when I try to use it with a virtual environment Stata shuts down as soon as I execute python:

I have activated the virtual environment using Powershelll prior to starting the Stata session.

PS D:\StataP> .\venv313\Scripts\activate
(venv313) PS D:\StataP>

    Python Settings
      set python_exec      D:\StataP\venv313\Scripts\python.exe
      set python_userpath  

    Python system information
      initialized          no
      version              3.13.0
      architecture         64-bit
      library path         C:\Python313\python313.dll
. python:

I would be gratful for any pointers as to what I am doing wrong.

Thank you.
