Introducing two updates.
1. Add param to He initialization scheme in torch.nn.init
Problem solved:
The function calculate_gain can take an argument to specify the type of non-linearity used. However, it wasn't possible to pass this argument directly to the He / Kaiming weight initialization function.
2. Add util to clip gradient value in torch.nn.utils.clip_grad
Problem solved:
DL libraries typically provide users with easy access to functions for clipping the gradients both using the norm and a fixed value. However, the utils clip_grad.py only had a function to clip the gradient norm.

Once Variable and Tensor are merged the existing Variable test would
cause an infinite recursion. Instead, modify the Variables directly
inside a `no_grad()` block.
The function iterates over columns and sets "sparsity" fraction of entires in each column to 0. The number of zeros in a column (num_zeros) is then ceil(rows*sparsity)
