[kriz232121]

i use tensorflow 1.14 with version of cuda and cnn 10 in virtual enviroment with anaconda and follow the steps on https://github.com/EdjeElectronics/TensorFlow-Object-Detection-API-Tutorial-Train-Multiple-Objects-Windows-10
i train the model but when i want to validate with image i have the issues
