无法从 1D 原始补丁到 2D 图像补丁 reshape.npy 数组

Question

Need to reshape 1-d 2914 pxls per picture array to 2-d 62*47 array, from a dataset

tried to creative a patches variable with np.load attached and then using np.shape(62,47) on said variable, got a "tuple isnt callable error"

Answer 1

np.shape is not a function. It returns the shape of your array, which is a tuple. You need to use the np.reshape function.

import numpy as np

pic = np.random.rand(2914)
print(f"Shape: {pic.shape}")

pic = np.reshape(pic, (62, 47))
print(f"Shape: {pic.shape}")

print(f"np.shape: {np.shape(pic)}")
print(f"type of np.shape: {type(np.shape(pic))}")
