Will it support for SparseTensor (Tensorflow or Pytorch)?

Hi, jonasrauber

Thanks for your works!

I wonder if it will add support for SparseTensor (Tensorflow or Pytorch), like this:

import numpy as np
import tensorflow as tf
import eagerpy as ep

x = np.array([[0, 1, 0],
              [0, 0, 1],
              [1, 0, 1]])

# Tensorflow SparseTensor
sp_x = tf.sparse.from_dense(x)

# eagerpy
# is it implemented?
sp_x = ep.assptensor(x)

We have no special support for sparse tensors at the moment. If the sparse TensorFlow tensors can be used like dense tensors, it might work. Adding explicit support for sparse tensors would probably only make sense if PyTorch and JAX support them as well.
