I am currently facing an issue with QGIS 3.8.3. In which I am unable to use Vector Tools and other plugins. Missing Vector Tools

Below are some of the trackbacks for the Python error. I am unable to show all due to the word count when posting the question:

I have re-installed QGIS many times and I am still facing this issue.

Any help or advice for this?

    how are you installing QGIS? are you installing the 32 or 64 bit version?

  • @IanTurton Hi Ian! Thank you for your reply! I am installing the 64 bit Standalone version of QGIS.

  • I was wondering if any pip installs of python modules via the Command Prompt could have resulted in this error. I did install python modules like numpy, sklearn and mlrose for my other python projects yesterday before opening QGIS today and discovering this issue.

  • it looks like it is trying to run the 64bit version as a 32 bit program - how are you installing qgis?

  • Hi @IanTurton ! Thank you for your reply! I am installing it via the QGIS homepage, the 64-bit Standalone version to be exact

I've resolved this problem by re-installing numpy. This seems to the problem here, as well : File "C:\Users\jerom\AppData\Roaming\Python\Python37\site-packages\numpy\_distributor_init.py". I guess there is a 32 bit numpy installation somewhere.

Go to OsGeo4w Shell and type py3_env. You should see Python variables. Then type pip uninstall numpy and pip install numpy.

PS. OsGeo4W shell is accessible from the same application folder as QGIS.
