This is an implementation of the normal convolution and the transposed convolution in Numpy. I have explained the work in details in this medium article. The main.ipynb file shows some comparisons with Tensorflow and Pytorch, and those tests can be found in tests.py which can be a guide for using the numpy implementation for your work. All components of the convolutions are covered in the conv2d_transpose_numpy.py file.

Thank you for your interest!
