UiPath Python Activities not working for 64 Bit Python Interprettor

Help Studio

Hi,

I have been trying to work with NLP/ML python libraries which work with 64 Bit Python Interpreter, but the problem is that UiPath is no longer supporting Python call via 64 Bit Interpreter. While at the same time it works fine with 32 bit

Any update or help on that will be really great?

Below is the error -

21.4.4+Branch.master.Sha.a8b5101efe02651274064093e9c7410fedff7696

Hi @Dawodm Thanks for reply.

But the issue is only with 64 bit interpreter of Python, with 32 bit I am able to run the python activities.

Do you have any work around on that?

It seems UiPath has provided fix in the new release for the Python activities, so working fine now
