How to handle data with python

Hello.
I have succeeded in running a great sample “manipulation: shuffle_box”.

So, I wanted to process the data with python based on this sample.

For example, color images and depth images sent from SIM.
I tried to bring the data onto python.

However, the sample code I created with reference to pick_and_place failed.

I think my perception is wrong. Help me.
