When i submit my exercise, i have a error "There was an error grading one or more parts of your submission. Please review the messages below for suggestions. Learner Error: Grader timed out Please try optimizing the efficiency of your solution and submit again. You can also visit the discussion forum to see if your peers have experienced and found resolutions for similar errors, or if course staff have provided prior guidance for these errors… If the error isn’t resolved in 24 hours, please reach out to Coursera through our Help Center." I use: one convolution layer with 64 feature map, callbacks when accuracy \> 99.8%. Can you help me, thank you very much! ---

I have the same issue as well. Tried reducing the filter size to 32 and have entered the batch\_size as 5. Still not able to resolve. Could you figure it out? ---

Without sharing code, could you please your model configuration? ---

One layer of convolution with a max pooling. And then the usual a flatten layer and dense layers. I changed the filter size to 32. After multiple attempts of submitting the same code, its finally successful for me. ---

Retrying submission at different times may work. I guess its a bug from coursera side. Kindly resolve this issue as its taking a lot of our time trying to figure out when the code is right from our end. ---

Hi everyone! Thank you for reporting and am glad that the submission went through for Farija. Hope naririn and Manh\_Truong\_Do have also passed the assignment. We are currently working on a solution for this so as not to block other learners. Hopefully, we can push it out before the end of the month.
