Error importing pynq on different board (Microzed)

I am trying to implement Pynq on Microzed 7020 and I have used the fork by ticktronaut

Writing the image, updating and launching the modified jupyter notebooks worked fine, but when I tried importing pynq I get the following error:

AttributeError Traceback (most recent call last)

AttributeError: ‘_TCL’ object has no attribute ‘family’

Any help would be very appreciated and feel free to ask for any more details you might requiremz_des_wrapper.zip (10.2 KB)

It would be easier to identify the problem if you can attach the original tcl file you used.

My guess, though, is that your PS block is wrapped in a hierarchical IP - make sure the PS block is exposed at the top level of your block design.

Thanks for the reply, I have since remade a new tcl file (attached) and have been specifying the full path to the file. It seems to have solved the issue
