problem with get_gradients

Anyone facing problem with the get_gradients?
Traceback (most recent call last):
File "ace_run.py", line 112, in

Hey @soumbane,

I face the same problem, did you manage to solve this?

Thanks,
Michael

For future readers who face the same problem:
The solution is that the recent TCAV version is incompatible with the current ACE implementation.
Install version 0.2 of tcav (pip install tcav==0.2 instead of pip install tcav), and it should work fine.

Hi @MichaelDoron,

Yes, I solved the issue. The positional argument is not required for TCAV. So setting the argument example to None works.

Thanks,
