The convolutional layer is too slow.

I implemented a convolutional layer and it turned out to be too slow. Since it takes too much time even to complete an epoch, I haven't been able to see if the network backpropagates correctly, it doesn't throw any errors but don't know if the loss gets down. Other parts of the code are fine, just this one needs some correction. Any help would be appreciated, thank you.
