[docs]class SummaryRecord:
"""
SummaryRecord is used to record the summary data and lineage data.
The API will create a summary file and lineage files lazily in a given directory and writes data to them.
It writes the data to files by executing the 'record' method. In addition to recording the data bubbled up from
the network by defining the summary operators, SummaryRecord also supports to record extra data which
can be added by calling add_value.
Note:
1. Make sure to close the SummaryRecord at the end, otherwise the process will not exit.
Please see the Example section below to learn how to close properly in two ways.
2. Only one SummaryRecord instance is allowed at a time, otherwise it will cause data writing problems.
3. SummaryRecord only supports Linux systems.
Args:
log_dir (str): The log_dir is a directory location to save the summary.
file_prefix (str): The prefix of file. Default: "events".
file_suffix (str): The suffix of file. Default: "_MS".
network (Cell): Obtain a pipeline through network for saving graph summary. Default: None.
max_file_size (int, optional): The maximum size of each file that can be written to disk (in bytes).
Unlimited by default. For example, to write not larger than 4GB, specify `max_file_size=4 * 1024 ** 3`.
raise_exception (bool, optional): Sets whether to throw an exception when a RuntimeError or OSError exception
occurs in recording data. Default: False, this means that error logs are printed and no exception is thrown.
export_options (Union[None, dict]): Perform custom operations on the export data.
Note that the size of export files is not limited by the max_file_size.
You can customize the export data with a dictionary. For example, you can set {'tensor_format': 'npy'}
to export tensor as npy file. The data that supports control is shown below. Default: None, it means that
the data is not exported.
- tensor_format (Union[str, None]): Customize the export tensor format. Supports ["npy", None].
Default: None, it means that the tensor is not exported.
- npy: export tensor as npy file.
Raises:
TypeError: If the parameter type is incorrect.
