I created a new environment in Anaconda 2.0.3 using Python 3.8.8 using conda create -y --name gpu_env python=3.8. In the next step, I install nb_conda using conda install nb_conda.

I repeatedly get the following error message at the execution stage

"The procedure entry point ?init@PyWinBufferView@@QEAA_NPEAU_object@@_N1@Z could not be located in the dynamic link library C:\Users\user123\anaconda3\envs\gpu2\Library\bin\pythoncom38.dll"

This happens during the 'enabling notebook extension nb_conda/main' , 'Enabling tree extension nb_conda/tree', and 'Enabling: nb_conda' as shown below

Executing transaction: \ Enabling nb_conda_kernels...
CONDA_PREFIX: C:\Users\user123\anaconda3\envs\gpu_env

      nb_conda 2.2.1 ok

done

The pythoncom38.dll is present in location specified in the error message. I tried the following without success:- (a) Delete the pythoncom38.dll from the environment folder, and thereafter reinstall nb_conda (b) Uninstall Anaconda, and reinstall without including the PATH variable (c) Other ideas given in this page and this page

I could not find a working solution.

Can anyone throw some way ahead?

  • I am having the same problem; does someone is able to get to a solution? I already tried to replace the python38.dll but with no avail – Carlo Dec 15 '21 at 11:15

I had the same problem and I suspect the file pythoncom38.dll on my environment was corrupted. So I replaced the file from my local environment and replaced it by the file pythoncom38.dll from the following website: https://www.pconlife.com/viewfileinfo/pythoncom38-dll/ and

I had a similar issue when I open Notebook on virtual machine. (Saw exactly same notification) I use anaconda, but one of my colleagues installed Python and then installed Anaconda too, before he passed the virtual machine to me. I removed both Python and Anaconda, and installed Anaconda only. And issue fixed.
