出现 Traceback (most recent call last): File "yymnist/make_data.py", line 114, in data[0] = make_image(data, image_paths[idx], ratio) File "yymnist/make_data.py", line 62, in make_image image = cv2.resize(image, (int(28ratio), int(28ratio))) cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\imgproc\src\resize.cpp:4045: error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize'

出现了同样的错误

我又用了自己的训练集测试可以了，不用yymnist。

When reading a image with imread, if the path doesn't exist, it will return a None without raising an error. A None object can't be resized, thus having an assertion failure. You may want to check the path of your training data.

我用自己的训练集发现报错如下： Traceback (most recent call last): File "make_data.py", line 111, in data[0] = make_image(data, image_paths[idx], ratio) IndexError: list index out of range
