ActivityNet v1.3 data preprocess & infernece

[fanqing-1116]

I downloaded all the sampled video data（32.4G), the total number of these videos is 14950. But the total number of all npy files I get after running step 3 is only 11171. When I run the RGB model inference I also get some FileNotFoundError like "No such file or directory: 'datasets/activitynet/train_val_npy_112/v_JDg--pjY5gg.npy'". I wish i can use some help.

@linchuming Hi, thanks for your work! I also met with the same problem when I preprocess the ActivityNet dataset. Specifically, when the duration time of a video is a little bit longer, I can not extract RGB and flow npy features. Would you mind giving me some help to figure it out.

@fanqing-1116 , did you try use 7za x -r train_val_112.7z and check the number of mp4 files is 14950?

Why the number of classes in ActivityNet-1.3 is set to 2 instead of 201. The paper does not mention it. So I am a little curious that it is a action proposal task in ActivityNet-1.3. Hope to get your reply, thank you~

@czhaneva you can refer to the answer of the issue #4 .

Hello, activitynet v1.3 can't download the data, can you itemize the data?
