Finetuning error question about c3d

[dutran]

@iamyup I think you got the same problem as #7, if you use videos, there some minor differences in term of UCF101 avi files and also codecs. So you may have problem with missing the last frames.
There are two options that you can try:

1. extract avi -> frames and regenerate the list file according to your real existing frames.
2. write script to check the number of frames for each avi file you have, base on that regenerate new list file based on the number of frames that you have.

Let me know if those options work for you

@dutran Thanks for your comment. I am trying second option.
I regenerated new list file based on the number of frames that I have.
I am running the finetuning example. I will let you know when I get the result.

Does the option work for you?

@dutran Sorry for late answer.
Thanks for your concern. Yes. It worked. and I finished the training.

And I modified the test list file for testing. I ran test and I got below error message while running test.

I regenerated the test list file based on the number of frames that I have.
Do you have some clue ?

@iamyup some of your clips in the testing list file are not available (or failed to read). I had a trigger that require testing to be completed (meaning not missing any clip). You can comment out the trigger (if you don't need exact accuracy, assuming missing some examples does not change much the final accuracy if your testing set is large) or check you list file and remove the failed examples.

@iamyup how do you count the number of frames?
i had the same problem using the number of frames you can read from file properties (like with opencv CV_CAP_PROP_FRAME_COUNT ) that sometime can be incorrect
you can solve counting the frames yourself or using an external tool to do the job ( i used ffprobe with the option -count_frames)

Hi @dutran and @hunter-87
Sorry for late reply and Thanks for your kind comments.

@dutran
Ok, I understood it now. I will make test list file again and let you know the result.

@hunter-87
Yes. I counted the number of frames using opencv with CV_CAP_PROP_FRAME_COUNT. I will try ffprobe as you mentioned.

@iamyup I think you may get your issue fixed now?

[iamyup]

Yes. I fixed the issue. Thanks.
Happy New Year~ :-)
