I passed all the test cases but getting this error.
That most likely means that there is something structural wrong with your notebook. The simplest version of that would be that your memory image is too large, because of running the training. The first thing to try is:
- Kernel → Restart and Clear Output
- Save
- Submit again
Please try that and let us know. Note that the grader does not need to see your generated output in the notebook. It only needs to call your functions.
If that doesn’t fix the problem, then the next step is more work: get a clean copy of the notebook using this topic on the DLS FAQ Thread. Then carefully “copy/paste” over just your completed code from the “YOUR CODE HERE” sections and then try submitting again.
But the hope is that the “Clear Output” will fix the problem.
The issue got resolved by restarting and clearing the output of the kernel. Thanks for your response.
