the naming "from_numpy" is misleading since we support now scipy compressed matrices as well
shall we rename it to something like "from_py_matrix", "from_array_like"?

We could also use something like "from_pydata" which merges the two separate methods from_numpy and from_pandas to single method, internally we could route to the corresponding handler based on the input instance type.
