test image folder can not be reused

[hannraoi]

Hi~it's me again and this time I have met another problem =)

The first time I run "t_folder=/xx/xx model_file=/xx/xx result_path=/xx/xx th run_test.lua" and it worked perfectly, which is nice, but after I change the test images under the same folder, it reminds me that a certain image file can not be found, the error info is like this:

hannraoi@hannraoi-B85M-DS3H:~/Photo-Realistic-Super-Resoluton-master$ t_folder=/home/hannraoi/my_srgan_test/ model_file=/home/hannraoi/my_srgan_model/super_resolution_adversarial_G_134 result_path=/home/hannraoi/my_srgan_result/ th run_test.lua

I know little about Lua, so I don't know where the problem comes from, I hope to get some help, thanks!

by the way, my solution to the problem is to create a new t_folder with a different name each time I run the test code.

Hi @hannraoi . How many images did you use from Image net to train the model? And which data did you test your model on?

I have trained on a data of faces (approx 200,000) till 50 epochs, but the results are not great.

hi~ @smahajan07
I'm sorry that I didn't use ImageNet data as my training data, I use my own data instead and the amount of data is a little less than urs.
