Error in "Train Deep learning Model" using Jupyter Notebook

[RDAltarez]

Hi, I am doing a deep learning pixel classification in my ArcGIS pro 2.9.  I export my training data through (see below image):

Unfortunately when I am trining my data in Jupyter notebook, I am getting the following error. Pls pardon my being a neophyte in this field, but your kind response to solve this problem is highly appreciated.

To give you more background. I  updated my software to 3.0, and now I am getting this error. Shall I set-up again my deep learning environment?

Many thanks!
