U-Net — all tests passed with grade 66/100

Course Q&A Deep Learning Specialization Convolutional Neural Networks

Hi,

For the Image Segmentation with U-Net assignment I have passed all the tests and got reasonable outputs. But the grader gives 66/100 and says “Code Cell UNQ_C3: Function ‘unet_model’ is incorrect”. Could anyone tell what is wrong with my code implementation?

Many thanks,
Carol

Are you still having an issue with this exercise?

Be sure you specify the number of filters in every conv_block() and upsampling_block().

Hi,
I’ve got the same problem. I checked the number of filters in all blocks. Used double in conv_blocks and half in upsampling blocks. My code seems correct and I passed all tests, but still got 66/100.

most probably inside the u-net function you put an actual number instead of the variable filter_num which you have to multiply or divide step-wise based on whether you are expanding or contracting the tensor

Yes, this was my fault, thank you @TMosh, @jgeng

Thanks Jgeng.
I was also doing the same mistake.
Finally got 100 instead of 66 on my programming assignment.
