C3W3:
/lab/tree/C3W3_Assignment.ipynb
i am having problem running cells
the cells keep running for hours but no output is there and i am getting “Server Connection Error”
rest of the labs are working fine.
Thanks for sharing your issue! Based on your description, it sounds like the kernel is hanging or crashing.
Some troubleshooting steps you can try include:
- Restart the kernel and clear all outputs: (
Kernel > Restart and Clear Outputs of All Cells...). Try running a simple cell (for example: print(“Hello”)) to check if the kernel is responsive. - If you are using Coursera Labs: try restarting the lab environment or even logging out and back in.
- Clear your browser cache and cookies: then reopen the lab. This helps refresh any stale sessions or cached connections that might be causing issues.
- Try creating a fresh notebook in the same lab directory: Sometimes notebooks themselves get stuck or corrupted.
If none of these work we can look at other possible causes!
