Can't start the script for some odd reason.

@Testin1234 That's because on Windows 10, Python 3 is run with python and not python3. I never tested the script on Windows, but I believe you can resolve the issue by modifying this line: https://github.com/ProGamerGov/Neural-Zoom/blob/master/neural_zoom.py#L187

Change run = 'python3 ' to run = 'python ', and that should resolve the issue.

@ProGamerGov It seems that it worked, but I am facing another issue. Capturing style target 1

I'm not sure why it would do this. Do I need to re-specify the directory or something?

[Testin1234]

Actually, that doesnt seem to be the problem. Is it just unable to make the images?

[ProGamerGov]

Try creating a folder called output_dir, as the code expects that folder to exist (and tries to create it).

[Testin1234]

Alright, did that and it still has the same error. Out of curiosity, I made a file in the output_dir called out_0000.png and it then had this issue: No such file or directory: 'output_dir/out_0001.png'

[ProGamerGov]

@Testin1234 What are the neural-zoom specific parameters that you are using?

[Testin1234]

python neural_zoom.py -script neural_style.py -style_image Color.jpg -content_image tubingen.jpg -model_file models/models/vgg19-d01eb7cb.pth -num_frames 20 -starting_image tubingen.jpg

[Testin1234]

Are my params wrong or something?

[ProGamerGov]

@Testin1234 Sorry, for the late response, so far I've found the slash direction to be a potential error source, but the error message still remains. Your parameters are not the cause, as I can reproduce the error.

[Testin1234]

Good to know that the error can be reproduced and I'm not messing it up. Hopefully this can be resolved soon.

[kyeshmz]

Okay, so I moved a bit forward with this.
Seems like the biggest problem here is with the tmp directories and how you are trying to keep the rendered version and a tmp dir.
Also a problem with starting_num and the -1 arguements against it.

I can make a PR but just want some insight on what you originally wanted to do.

[ProGamerGov]

@kkshmz It's been a long time since I created the code (and I was a lot worse at programming back back), but I seem to recall the one directory was for un-cropped images, and the other one was for cropped versions of the image. There is probably a better way to go about things though.
