Trying to convert tuple with ndarrays inside to another ndarray with additional dimension

Question

Suppose I have tuple a, which elements are np.ndarrays and I want to convert a to np.ndarray too. Like this:

a = np.ndarray(a)

But getting such error: only integer scalar arrays can be converted to a scalar index. Tried also to convert inner arrays to the list, but got incorrect results. If my inner arrays have 3 dimensions, after all I want to have a ndarray with 4 dimensions. How can I do that? Thanks

Answer 1

I believe the numpy.ndarray is not for creating with data.

The docs say:

Arrays should be constructed using array, zeros or empty (refer to the See Also section below). The parameters given here refer to a low-level method (ndarray(…)) for instantiating an array.

Try using numpy.array .

Your error would be that the tuple is for the first argument shape which is a tuple of integers.

You could create one from scratch with np.ndarray and the correct tuple instead perhaps.
