AttributeError: module 'tensorflow.python.ops' has no attribute 'convert_to_tensor_v2'I tried running your colab notebook with the mnist data and the amazon data but came up with this error

Hello,
Thanks for letting me know about this issue! It appears that changes in Tensorflow 2.3 break the package right now, so I've updated the colab notebook to run on TF 2.2 in the short term. I will leave this issue open until I fix the package for TF 2.3.
Appreciate it,
Chris
lucasace commented
I actually fixed it by just changing the following line in loss.py to
y_pred = ops.convert_to_tensor_v2(y_pred)to
y_pred = tf.convert_to_tensor(y_pred)Hope this helps
ck37 commented
Yep, I followed that such a change would fix it for TF 2.3, but does it also work in TF 2.2? That's the other check before making the change, otherwise it will be more of a pain to maintain TF 2.2 compatibility.
lucasace commented
Sorry for the late reply
tf.convert_to_tensor()does work in TF 2.2 cause its base is derived from TF 1.0, therefore i think you can make the change and close this issue
