python-2.7 - cv2.error: OpenCV(4.1.0) /io/opencv/modules/imgproc/src/resize.cpp:3555: 错误: (-215:Assertion failed) func != 0 && cn <= 4 in function'resize'

问题描述

我正在尝试使用 cv2.resize 调整 (720,1280,3) 数组的大小，

data['motion_vector'] = cv2.resize(data['motion_vector'], (int(feat_shape[0][3]), int(feat_shape[0][2])), interpolation = cv2.INTER_AREA)

但我遇到了这样的错误：

Traceback (most recent call last):

    train_end2end.main()
