Hello, I have Python Scope and Run Python Script activities. The Python function “report\_genertor()” works fine manually running in IDE, takes csv file and using pandas groups and calculates data, then writes to csv file. When I run the program in UiPath, I get the following error:  
RemoteException wrapping System.InvalidOperationException: Error initializing Python engine —\> RemoteException wrapping System.InvalidOperationException: Python instantiation exception  
Python Invoker program exception:  
Exception has been thrown by the target of an invocation.

I have tried running the Python function in UiPath from where python.exe file is located as well as using the venv location, I think the problem might be importing Pandas. Can anyone give me any advice or suggestions please? Thank you
