[docs]class SummaryCollector(Callback): """ SummaryCollector can help you to collect some common information. It can help you to collect loss, learning late, computational graph and so on. SummaryCollector also enables the summary operator to collect data from a summary file. Note: 1. Multiple SummaryCollector instances in callback list are not allowed. 2. Not all information is collected at the training phase or at the eval phase. 3. SummaryCollector always record the data collected by the summary operator. Args: summary_dir (str): The collected data will be persisted to this directory. If the directory does not exist, it will be created automatically. collect_freq (int): Set the frequency of data collection, it should be greater then zero, and the unit is `step`. Default: 10. If a frequency is set, we will collect data when (current steps % freq) equals to 0, and the first step will be collected at any time. It is important to note that if the data sink mode is used, the unit will become the `epoch`. It is not recommended to collect data too frequently, which can affect performance. collect_specified_data (Union[None, dict]): Perform custom operations on the collected data. Default: None. By default, if set to None, all data is collected as the default behavior. You can customize the collected data with a dictionary. For example, you can set {'collect_metric': False} to control not collecting metrics. The data that supports control is shown below. - collect_metric: Whether to collect training metrics, currently only the loss is collected. The first output will be treated as the loss and it will be averaged. Optional: True/False. Default: True. - collect_graph: Whether to collect the computational graph. Currently, only training computational graph is collected. Optional: True/False. Default: True. - collect_train_lineage: Whether to collect lineage data for the training phase, this field will be displayed on the lineage page of Mindinsight. Optional: True/False. Default: True. - collect_eval_lineage: Whether to collect lineage data for the evaluation phase, this field will be displayed on the lineage page of Mindinsight. Optional: True/False. Default: True. - collect_input_data: Whether to collect dataset for each training. Currently only image data is supported. Optional: True/False. Default: True. - collect_dataset_graph: Whether to collect dataset graph for the training phase. Optional: True/False. Default: True. - histogram_regular: Collect weight and bias for parameter distribution page and displayed in MindInsight. This field allows regular strings to control which parameters to collect. Default: None, it means only the first five parameters are collected. It is not recommended to collect too many parameters at once, as it can affect performance. Note that if you collect too many parameters and run out of memory, the training will fail. keep_default_action (bool): This field affects the collection behavior of the 'collect_specified_data' field. Optional: True/False, Default: True. True: it means that after specified data is set, non-specified data is collected as the default behavior. False: it means that after specified data is set, only the specified data is collected, and the others are not collected. custom_lineage_data (Union[dict, None]): Allows you to customize the data and present it on the MingInsight lineage page. In the custom data, the type of the key supports str, and the type of value supports str, int and float. Default: None, it means there is no custom data. collect_tensor_freq (Optional[int]): The same semantics as the `collect_freq`, but controls TensorSummary only. Because TensorSummary data is too large to be compared with other summary data, this parameter is used to reduce its collection. By default, The maximum number of steps for collecting TensorSummary data is 20, but it will not exceed the number of steps for collecting other summary data. Default: None, which means to follow the behavior as described above. For example, given `collect_freq=10`, when the total steps is 600, TensorSummary will be collected 20 steps, while other summary data 61 steps, but when the total steps is 20, both TensorSummary and other summary will be collected 3 steps. Also note that when in parallel mode, the total steps will be splitted evenly, which will affect the number of steps TensorSummary will be collected. max_file_size (Optional[int]): The maximum size in bytes of each file that can be written to the disk. Default: None, which means no limit. For example, to write not larger than 4GB, specify `max_file_size=4 * 1024**3`. Raises: ValueError: If the parameter value is not expected. TypeError: If the parameter type is not expected. RuntimeError: If an error occurs during data collection.
