问题遇到的现象和发生背景
使用cv2的dnn模块超分辨率出现
cv2.error: OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-5rb_9df3\opencv\modules\dnn\src\dnn.cpp:3520: error: (-215:Assertion failed) total(os[i]) > 0 in function 'cv::dnn::dnn4_v20201117::Net::Impl::getLayerShapesRecursively'
问题相关代码，请勿粘贴截图
import cv2
import os
from cv2 import dnn_superres
sr = dnn_superres.DnnSuperResImpl_create()
path = "G:\\122\\LapSRN_x8.pb"
sr.readModel(path)
sr.setModel("lapsrn", 8)
def read_path(file_pathname):
for filename in os.listdir(file_pathname):
print(filename)
img = cv2.imread(file_pathname+'/'+filename,3)
res = sr.upsample(img)
cv2.imwrite('G:\\A-1-3'+"/"+filename,res)
read_path("G:\\A-1-2")
运行结果及报错内容
