Hi @Shahabud_Din, This is odd. One possibility is that the grader is trying to grade an un-edited version of the assignment. The grader will test against using the original filename (C1W1\_Assignment, in this case), so if you made a copy and edited that file, that could be the problem. Another possibility is if you inadvertently changed the URI path. Please take a look at this other post for more details and post back here after you try out the suggestions. > [@Grader Error: Not able to detect variables](https://community.deeplearning.ai/t/grader-error-not-able-to-detect-variables/132828): > > Hello everyone I went through all the conversations about the grader bug. I have updated the lab version, passed all public tests and clearly defined all the variables. Even after getting the desired output, I still got a 03/10 for my submission. The name of the assignment file is: C1W1\_Assignment Grader Output: [ValidateApp | INFO] Validating ‘/home/jovyan/work/submitted/courseraLearner/W1\_Assignment/C1W1\_Assignment.ipynb’ [ValidateApp | INFO] Executing notebook with kernel: python3 2022… --- _[View the full topic](https://community.deeplearning.ai/t/c1w1-grader-output-error-all-the-tests-have-been-passed-but-the-grader-shows-error/150897)._
