Troubleshoot Error with Tensorflow-Python #16
Description
Hi,
I am getting following error message when executing a python project in Jupiter using Tensorflow version 1.15.2 on Mac OS. Please suggest me any solution for this error.
"ValueError: Tried to convert 'input' to a tensor and failed. Error: None values not supported."
