Detailed description

I have a lenet keras model that was trained for car color recognition. I converted it to tensorflow pb file using keras_to_tensorflow from https://github.com/amir-abdi/keras_to_tensorflow I created pbtxt with the keras_to_tensorflow. I tried loading it (cvInference.py) (cvInference.py)

cvNet = cv.dnn.readNetFromTensorflow('d:\tfs\LPR\IP\MAIN\SRC\PythonProjects\Keras\lenetcarColor.pb',
cv.dnn.readNetFromTensorflow('d:\\tfs\\LPR\\IP\\MAIN\\SRC\\PythonProjects\\Keras\\lenetcarColor.pb',
 'd:\tfs\LPR\IP\MAIN\SRC\PythonProjects\Keras\lenetcarColor.pbtxt')
'd:\\tfs\\LPR\\IP\\MAIN\\SRC\\PythonProjects\\Keras\\lenetcarColor.pbtxt')

I got the error: error:

cv2.error: OpenCV(3.4.3) C:\projects\opencv-python\opencv\modules\dnn\src\tensorflow\tf_importer.cpp:614: error: (-215:Assertion failed) const_layers.insert(std::make_pair(name, li)).second in function 'cv::dnn::experimental_dnn_34_v7::`anonymous-namespace'::addConstNodes'
