Procedure entry point gzdirect could not be located in the dynamic link library

Question

I tried to run the below command

conda create --name tf_gpu tensorflow-gpu

and it throws the error

Traceback (most recent call last): File "C:\Users\alexk\Anaconda3\lib\site-packages\conda\exceptions.py", line 1062, in call

OSError: [WinError 127] The specified procedure could not be found

and also a error window pops up saying:

The procedure entry point gzdirect could not be located in the dynamic link library C:\User\\Anaconda3\Library\bin\libxml2.dll

I am answering quite lately but I had a similar issue recently and this post was the closest to my issue (and had no answers).

The issue for me though was that I was trying to communicate with matlab from c++ code (using visual c++ in visual studio).

After searching a long time, I discovered that gzdirect came from zlib1.dll and not libxml.

What caused this issue for me was that I added the path to the matlab dlls at the end of my path environnment variable and because of that, a zlib from my system was used instead of Matlab Zlib.

All I had to do was to add the path to Matlab's DLL at the start of my path and not at the end.
