i run this code.

import numpy as np
import matplotlib.pyplot as plt
from PIL import Image
X_train = plt.imread('00_0.9944__20150716_131647_04249_074.raw_color.bmp')
type(X_train)
X_train = X_train.resize((32, 32))    
X_train = X_train.reshape((len(X_train), 3, 32, 32))

then, it throws

X_train = X_train.reshape((len(X_train), 3, 32, 32))

AttributeError: 'NoneType' object has no attribute 'reshape'

using img size is 207x209. Please help me. Thank you.

It is possible to return a value of type None, check the type of X_train in the following lines:

X_train = X_train.resize((32, 32))
type(X_train)    
X_train = X_train.reshape((len(X_train), 3, 32, 32))
type(X_train)

only the type of array can use reshape() and it can not change the number of the data your array contains. Maybe you can try something like this:

import numpy as np
from PIL import Image
import matplotlib as plt

x_train = Image.open('skyscraper.jpg')
x_train = x_train.resize((32,32))
x_train = np.array(x_train)
x_train = x_train.reshape((3,32,32))
print(x_train)
