Basically I want to change the tensors provided by numpy.ndarray.
For example, I want to do something like this (latex notation)
A_ {i, j, k, l, m, n, p} → A_ {i, jk, lm, np}
or
A_ {i, j, k, l, m, n, p} → A_ {ij, k, l, m, np}
where A is ndarray. i, j, k, ... denotes the original axis.
so that the new axis 2 becomes a flattened version of axis 2 and 3, etc. If I just use numpy.reshape, I don’t think it knows which axes I want to combine, therefore it seems ambiguous and erroneous minded.
Is there any neat way to do this and not create another ndarray manually?
