Dumping numpy array into an excel file

Question

I am trying to dump numpy array into an excel file using savetxt method, but I am getting this weird error on the console:

.18e,%.18e,%.18e,%.18e,%.18e,%.18e         


        

Answer 1

Bit late, but might help others facing such an issue.

This error is because you appear to have set

dtype = np.ndarray

when creating / defining your Numpy matrix first_layer_output.

One solution to this problem is modifying your command storing the

np.savetxt('test.csv', first_layer_output, delimiter=',', fmt='%s')

This command now outputs the contents of the array as a string, irrespective the actual data types being used. Hope this helps.
