class MySVM : public CvSVM 是否缺少CvSVM的檔案或定義檔

opencv3没有CvSVM函数，opencv2.4有，请确认opencv版本号。

SVM_HOG.xml里只有一个支撑向量？

对于线性SVM，svm.train函数中封装了void CvSVM::optimize_linear_svm()函数，使得多个支持向量整合为一个，这只是形式上的变化，详见svm.train()函数源码

Can you provide relevant files about the activitynet1.3 dataset

Hi！what does the anet_train_video.txt look like？

@mondalanindya @duanmushuangquan Hi! Did anyone find any fix?

I have fixed it. I set train_cfg, and optim_wrapper to none and it works. @mondalanindya @duanmushuangquan

thumos rgb feature extraction

> Hi, I'm having some issues extracting the rbg features for the thumos dataset. In particular, in the mmaction2 dataset there are two files for feature extraction: [https://github.com/open-mmlab/mmaction2/blob/0.x/tools/misc/clip_feature_extraction.py](url) and [https://github.com/open-mmlab/mmaction2/blob/0.x/tools/data/activitynet/tsn_feature_extraction.py](url),...
