Awesome project! Question about rescale the feature length.

[ideaRunner]

Thanks for sharing!
The inference speed is extremely faster with a better result.
I'm thinking about how to reproduce the result on other datasets.
Could you share some detail or insight about how to use linear interpolation to rescale the feature length of all videos to same length 100 ?

Any method function, reference papers or codes will be thankful.

Hello, do you have the code to reproduce this article? The author has no working training code. How do you reason?

@ideaRunner
After you use TSN to extract video features, the features length is different. You must reshape these features by fitting and interpolation functions.

Hi @pengxiaoxiao
With these inference codes，you can repeat the results in our paper.

yean, thank you!

why?

[lijiannuist]

@pengxiaoxiao
check your tensorflow version

[pengxiaoxiao]

Tensorflow-gpu == 1.9.0
Python == 3.6

@lijiannuist Yes, even some video's feature-length is less than 100, it must be fixed-length to feed into the network.
Thank you for sharing such kind of straightforward code!

@pengxiaoxiao Hi, pengxiaoxiao. For now, I am going to reproduce the inference results.
It is better to re-open an issue as your question is not related to this one.
The more detailed information about this issue, the more accurate the solution you will get.

thank you! I solved it by g++-5!

How to extract features with TSN? Is removing the FC layer of TSN a feature?
