C3W2_Assignment.ipynb - Zombie programming assignment spins until killed executing cell below. This loads specific old versions of various packages apparently required by the grader. Suggestions on how to best process are most welcome. Thanks, Matthew 
# For compatibility. Pin tf-models-official version so it will use Tensorflow 2.15.
!sed -i ‘s/tf-models-official>=2.5.1/tf-models-official==2.15.0/g’ ./models/research/object_detection/packages/tf2/setup.py
# Compile the Object Detection API protocol buffers and install the necessary packages
!cd models/research/ && protoc object_detection/protos/*.proto --python_out=. && cp object_detection/packages/tf2/setup.py . && python -m pip install .
Thank you for pointing this out.
I tried running the lab myself using the same settings, and I’m experiencing a delay. The code runs, but one specific line is taking an unusually long time (around 10 minutes) and does not seem to complete as expected.
@chris.favila, could you please check if there might be any recent updates or issues affecting this part of the lab? It would be helpful to know whether this is expected behavior or if something needs to be adjusted.
Hi, and thank you for reporting! Please give us the next 24 hours to investigate and resolve this issue. Please move on to the next part of the course in the meantime. Thanks again.
is this from the download checkpoint part??
your download checkpoint part looks incorrect!!!
Appreciate the help. I’ll move on & hopefully come back. Here’s the error messages when allowed to run for 1 hour+. Thanks, Matthew

@matthew_tucker
which part of the exercise code throws this error?
Hello again. We’ve identified the issue and it might take longer to fix. This is due to updates in Colab which affects the initial setup of the required packages. We’ve temporarily locked the item on Coursera. Target resolution is by end of this week. Thank you and I’m sorry for the experience. We will fix this as soon as possible.
Hi! The lab is now fixed. You can reopen it from the classroom to load the changes. Thank you!
