I want to change my array type as pd.DataFrame
but its shape is:
array_.shape
(1, 181, 12)
I've tried to reshape by the following code, but it didn't work:
new_arr = np.reshape(array_, (-1, 181, 12))
How can I change its shape?
CodePudding user response:
You may want to erase the -1
parameter from the reshape()
function to get a final output shape of (181, 12)
import numpy as np
m = np.array([[[1]*12]*181])
n = np.reshape(m, (181, 12))
print(m.shape, n.shape)
Output:
(1, 181, 12) (181, 12)
CodePudding user response:
NumPy array dimensions can be reduced using various ways; some are:
using np.squeeze
:
array_.squeeze(0)
using np.reshape
:
array_.reshape(array_.shape[1:])
or with using -1
in np.reshape
:
array_.reshape(-1, m.shape[-1])
# new_arr = np.reshape(array_, (-1, 12)) # <== change to your code
using indexing
