Not able to load "SentenceTransformer" package in python script

Help Studio

Only when “SentenceTransformer” (NLP based python library) imported in the python script and executed, I’m getting below error while execution.

Note: Installed “SentenceTransformer” library in the python execution environment imported in Uipath.
Otherwise the same code is working fine in the command prompt outside Uipath.

@MAHALAKSHMI_S any solution for this?

Hi @Atul_Rai , UiPath does not support loading some advanced python libraries like SentenceTransformers.

Instead of integrating the python script via Python scope in UiPath, you can call the script via powershell command.

Thank you so much @MAHALAKSHMI_S

I wasted my one week but thought the same solution you suggested.

One strange observation is that it is working in other machine but not at my machine.
