About saving npy files

[htowa]

sorry

When extracting features from a video and saving it as an npy file, it seems that "video_name_timestamps_ms and video_name_fps" are also saved together.

How can I avoid saving these files and only save "video_name_rgb"?

sorry about the super late reply. i've missed it completely.

it is easy to fix by commenting the keys you don't wanna save:

video_features/models/_base/base_framewise_extractor.py

Lines 75 to 79 in 1b67c9f

	features_with_meta = {
	self.feature_type: np.array(vid_feats),
	'fps': np.array(video.fps),
	'timestamps_ms': np.array(timestamps_ms)
	}

and

video_features/models/_base/base_flow_extractor.py

Lines 96 to 99 in 1b67c9f

	features_with_meta = {
	self.feature_type: np.array(vid_feats),
	'fps': np.array(video.fps),
	'timestamps_ms': np.array(timestamps_ms)

depending on the feature extractor you are using.

also, I'd love to merge a pull request that implements it.

保存したくないキーをコメントすることで簡単に修正できます。

video_features/models/_base/base_framewise_extractor.py

Lines 75 to 79 in 1b67c9f

	features_with_meta = {
	self.feature_type: np.array(vid_feats),
	'fps': np.array(video.fps),
	'timestamps_ms': np.array(timestamps_ms)
	}

そして

video_features/models/_base/base_flow_extractor.py

Lines 96 to 99 in 1b67c9f

	features_with_meta = {
	self.feature_type: np.array(vid_feats),
	'fps': np.array(video.fps),
	'timestamps_ms': np.array(timestamps_ms)

使用している特徴抽出器によって異なります。

また、それを実装するプルリクエストをマージしたいと思います。

I see, TXH!

Hi Author @v-iashin

You defined this attribute:

https://github.com/v-iashin/video_features/blob/master/models/_base/base_framewise_extractor.py#L44

as output_feat_key, If we pass the value as self.output_feat_keys = [self.feature_type], will it only save feature_type npy files?
