You can ignore those errors then, even when i took that assignment I had those. As far as I know some of them are errors that are thrown from incompatibilities and enviroment settings…

But problem is my submission is not passing .

Thats what I asked you in the beginning. There are no problems with the assignment because I just passed it myself.

At this point I suggest you perform a notebook reset and start from the scratch again, I am not sure where the error might be.

I am also facing the same issue, passed all test cases but getting same error as your can you help me to fix it?

10

Did you perform a reset on the notebook thats what I sugessted above. Maybe @Bonny_Patel can tell us what worked for him as well.

11

Error got resolved as i commented the code of training block

12

Please, can you tell me how you did it? What do you mean by commenting the code of training block?
Because, I am facing the same problem.

13

@Seli_Rasulzade, try choosing the “Restart and Clear Output” option on the Kernel menu before you submit.

14

I reset the notebook as @gent.spah suggested. Re-ran the notebook and submitted.

16

i am facing a problem it is taking too much time to run whole of program… if i submit in between it give a big error but if after restart and clear output i am getting another with pass bot still 0 score
