Problem testing data

[pendex900x]

When I use python test_LPRNet.py the output:

Successful to build network!
load pretrained model successful!
Traceback (most recent call last):

Why it happends?

I have met with the same problem！

[pendex900x]

Finally I could not solve it:/ please let me know if you find an alternative solution

[JKLove21]

Bro, I worked it out! The reason is that opencv cannot read the image file path when it contains Chinese characters

I rewrite a new function as def cv_imread(file_path): cv_img = cv2.imdecode(np.fromfile(file_path, dtype=np.uint8), -1) return cv_img You just need to paste it at the end of load_data.py

Then you substitute the original sentences as follows filename = self.img_paths[index] Image = cv_imread(filename)

It will be ok, you can try it

Wow, I spent hours watching how to fix it and you did it! haha, I got lost in the last part, could you upload the file? I have already created a new function in load_data.py

You can check the txt.

Thanks, When I try the file python test_LPRNet.py

The output is:

I think I'm doing something wrong or my computer doesn't have those Chinese character fonts

[JKLove21]

Bro, It can work on my computer.  I can run the test. py successfully.  Your guess maybe right.  I think you need to chage the test dataset cause it's Chinese license.  Wish you a good luck

an easy... use pil read the image and then use cv to convert the pil,finally you can fix it
