Video

class Video

Format a video for logging to W&B.

Args:

• data_or_path: Video can be initialized with a path to a file or an io object. The format must be “gif”, “mp4”, “webm” or “ogg”. The format must be specified with the format argument. Video can be initialized with a numpy tensor. The numpy tensor must be either 4 dimensional or 5 dimensional. Channels should be (time, channel, height, width) or (batch, time, channel, height width)
• caption: Caption associated with the video for display.
• fps: The frame rate to use when encoding raw video frames. Default value is 4. This parameter has no effect when data_or_path is a string, or bytes.
• format: Format of video, necessary if initializing with path or io object.

Examples:

Log a numpy array as a video

import numpy as np
import wandb

run = wandb.init()
# axes are (time, channel, height, width)
frames = np.random.randint(low=0, high=256, size=(10, 3, 100, 100), dtype=np.uint8)
run.log({"video": wandb.Video(frames, fps=4)})
