Encounter error in step 6 train the model. Could anyone help on this?

what's your python and TF version?

[csyeungad]

I am using python 3.11 and tensorflow 2.13. I think the problem is with the python version.

I am using python 3.11 and tensorflow 2.13. I think the problem is with the python version.

Try python 3.10.6 and TF 2.10.0 python 3.10.6 is most stable version and TF 2.10 is suitable for windows coz after 2.10 they officially dropped support for windows.

Thanks for you help. I tried to create a new environment with python 3.10.6.

However, when I run this cell, it installs TF2.13 automatically. Do I just uninstall TF and install TF2.10 again to solve it? Not sure if this is the proper way to do it.

You can do that.
