I have a data set I loaded with cv2, but when I try to format it I get the above error. I start by moving the data into
X_test (the loaded data is in
X_train =  X_test =  # Image matrices are different sizes so I am making them the same size for i in range(len(x_train)-1): resized = cv2.resize(x_train[i], (img_width, img_height)) X_train.append(resized) for i in range(len(x_test)-1): resized = cv2.resize(x_test[i], (img_width, img_height)) X_test.append(resized) # Convert to numpy arrays X_test = np.array(X_test) X_train = np.array(X_train) # Gather statistics print(X_train.shape) # -> (2734, 132, 126, 3) print(X_train.size) # -> 136415664 print(len(X_train)) # -> 2734 # Convert to black and white X_train = X_train/ 255. X_test = X_test/ 255. # First line throws error X_train = np.reshape(X_train, (len(X_train), img_height, img_width, 1)) X_test = np.reshape(X_test, (len(X_test), img_height, img_width, 1))
What am I doing wrong?
