运行这行代码时我收到此错误：
pixels.append( cv2.resize(cv2.imread(raw_folder + folder +"/" + file),dsize=(128,128)))**
错误：
cv2.error: OpenCV(4.5.2) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-vi271kac\opencv\modules\imgproc\src\resize.cpp:4051:
error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize'
