Dump a NumPy array into a csv file
If you want to save your numpy array (e.g. your_array = np.array([[1,2],[3,4]])) to one cell, you could convert it first with your_array.tolist().
Then save it the normal way to one cell, with delimiter=';'
and the cell in the csv-file will look like this [[1, 2], [2, 4]]
Then you could restore your array like this:
your_array = np.array(ast.literal_eval(cell_string))
Is there a way to dump a NumPy array into a CSV file? I have a 2D NumPy array and need to dump it in human-readable format.
