Hi Roberto,

I've asked a similar question a while ago on this forum and the feedback that I received was that generally speaking it's not a good idea to upgrade specific python libraries within FME.

Have you tried using a different python interpreter in FME?

Hi @kd​ ,

I will go for a different Python interpreter as soon as possible. I think it is a good compromise. For now, I need to stay for the standard one because of both 2.7 and 3.7 versions in FME Server.

@roberto​ , I'm not sure in what order of precedence it gets checked or cascaded to the Python interpreter, but you could instead try installing Pandas and its dependencies to the FME project folder itself with

> pip install pandas -target FMEProjectFolderPath and hopefully also install the correct version of NumPy here as well.

Executing a Python script within a workflow from a FMW file stored in FMEProjectFolderPath may check here first for Python modules and dependencies and avoid needing to play with interpreter path settings.

Hi @roberto​ 

As @kd​  mentioned, it is not recommended to upgrade the shipped modules.

If you do not need to use the latest version of the pandas module, you can try downloading an older version that is compatible with the shipped numpy module. For example, downloading pandas version 1.0.5 will work as it requires numpy 1.13.3 and higher. You can do so with this command:

fme python -m pip install pandas==1.0.5 --target <your_target_path>

I hope this helps.
