fdZ xZS )HFSummaryWriteraq
Wrapper around the tensorboard's `SummaryWriter` to push training logs to the Hub.
Data is logged locally and then pushed to the Hub asynchronously. Pushing data to the Hub is done in a separate
thread to avoid blocking the training script. In particular, if the upload fails for any reason (e.g. a connection
issue), the main script will not be interrupted. Data is automatically pushed to the Hub every `commit_every`
minutes (default to every 5 minutes).
`HFSummaryWriter` is experimental. Its API is subject to change in the future without prior notice.
Args:
repo_id (`str`):
The id of the repo to which the logs will be pushed.
logdir (`str`, *optional*):
The directory where the logs will be written. If not specified, a local directory will be created by the
underlying `SummaryWriter` object.
commit_every (`int` or `float`, *optional*):
The frequency (in minutes) at which the logs will be pushed to the Hub. Defaults to 5 minutes.
squash_history (`bool`, *optional*):
Whether to squash the history of the repo after each commit. Defaults to `False`. Squashing commits is
useful to avoid degraded performances on the repo when it grows too large.
repo_type (`str`, *optional*):
The type of the repo to which the logs will be pushed. Defaults to "model".
repo_revision (`str`, *optional*):
The revision of the repo to which the logs will be pushed. Defaults to "main".
repo_private (`bool`, *optional*):
Whether to create a private repo or not. Defaults to False. This argument is ignored if the repo already
exists.
path_in_repo (`str`, *optional*):
The path to the folder in the repo where the logs will be pushed. Defaults to "tensorboard/".
repo_allow_patterns (`List[str]` or `str`, *optional*):
A list of patterns to include in the upload. Defaults to `"*.tfevents.*"`. Check out the
[upload guide](https://huggingface.co/docs/huggingface_hub/guides/upload#upload-a-folder) for more details.
repo_ignore_patterns (`List[str]` or `str`, *optional*):
A list of patterns to exclude in the upload. Check out the
[upload guide](https://huggingface.co/docs/huggingface_hub/guides/upload#upload-a-folder) for more details.
token (`str`, *optional*):
Authentication token. Will default to the stored token. See https://huggingface.co/settings/token for more
details
kwargs:
Additional keyword arguments passed to `SummaryWriter`.
Examples:
