In Python 3.8.2, I want to create an array that has two dementions. You can see as below:
import numpy as np
array1 = [2.32, 6.888, 3.4, 9.01]
array2 = [67, 23, 99.80]
print(np.array([array1, array2],dtype = float))
But when I run I get an error ValueError: setting an array element with a sequence
Traceback (most recent call last):
File "main.py", line 4, in <module>
print(np.array([array1, array2],dtype = float))
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2,) + inhomogeneous part.
how can I resolve it? Thanks for any solution!!
Have 2 answer(s) found.

Two of your arrays have the same number of items. You can see
array1variable has 4 value items andarray2only has 3 value items.You can fix like that:
import numpy as np array1 = [2.32, 6.888, 3.4] array2 = [67, 23, 99.80] print(np.array([array1, array2],dtype = float))happy code!!

if my array is :
example_array = [[1,2,3],[1,2]]
Then I will get an error :
ValueError: setting an array element with a sequence.
but if I add padding then :
example_array = [[1,2,3],[1,2,0]]
Now it's working.
