How to Redirect Tensorflow Logging to A File?

To redirect TensorFlow logging to a file, you can follow these steps:

1. Import the logging module from TensorFlow:

1
2

import tensorflow as tf
import logging

1. Set the TensorFlow logging level to the desired level. You can choose from DEBUG, INFO, WARNING, ERROR, or FATAL. For example, if you want to set the logging level to INFO, use:

1

tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.INFO)

1. Set the log file path to which you want to redirect the logs:

1

log_file = "path/to/log_file.txt"

1. Configure the logging to write the TensorFlow logs to the specified file:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

# Create a file handler
file_handler = logging.FileHandler(log_file)
# Set the log message format
formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
file_handler.setFormatter(formatter)

# Get the TensorFlow logger
logger = tf.get_logger()
# Set the logger handler to the created file handler
logger.addHandler(file_handler)

From this point forward, all the TensorFlow logs will be redirected to the specified log file. To test the setup, you can try running TensorFlow code that generates logs and check if they are written to the file.

Remember to replace "path/to/log_file.txt" with the actual path of the log file on your system.

How to configure different log levels for different TensorFlow modules?

To configure different log levels for different TensorFlow modules, you can follow these steps:

1. Import the logging module from TensorFlow:

1

import logging

1. Set the root log level to the lowest level you want to see in any module:

1

logging.getLogger().setLevel(logging.INFO)

1. Specify log levels for specific TensorFlow modules or packages. For example, to set the log level for the tf package to DEBUG level:

1

logging.getLogger('tensorflow').setLevel(logging.DEBUG)

1. Optionally, set log levels for other TensorFlow modules or packages in a similar manner.

Note: The module or package names in the loggers follow the Python package hierarchy. For example, the logger for the tf.keras package can be set as logging.getLogger('tensorflow.keras').

Here's an example configuration that sets the root log level to INFO, TensorFlow log level to DEBUG, and Keras log level to WARNING:

1
2
3
4
5

import logging

logging.getLogger().setLevel(logging.INFO)
logging.getLogger('tensorflow').setLevel(logging.DEBUG)
logging.getLogger('tensorflow.keras').setLevel(logging.WARNING)

By configuring different log levels for different modules, you can control the amount of logging output and focus on the specific information you need.

How to handle log files in distributed TensorFlow training?

When it comes to handling log files in distributed TensorFlow training, here are a few steps you can follow:

1. Configure logging: Set up the logging framework in your TensorFlow code to capture the desired logs. TensorFlow provides the tf.compat.v1.logging module for this purpose. You can set the log level, log format, and log file path.
2. Use log synchronization: Configure TensorFlow to synchronize the logs across all distributed workers. This ensures that logs from all workers are saved in a coordinated manner. One way to achieve this is by setting the TF_CONFIG environment variable, which provides the cluster configuration to each worker. TensorFlow uses this information to synchronize logs.
3. Include worker information in log files: To differentiate logs produced by different workers, include worker-specific information in the log file name or format. This helps identify which worker generated a particular log entry. For example, you can include the worker's task index or task ID.
4. Handle log file storage: Decide where to store the log files. You can save them either locally on each worker or in a centralized location accessible to all workers. If you choose the latter, ensure that the location is write-accessible to all workers.
5. Implement log rotation: Since TensorFlow training can generate a large number of log files, it's best to implement log rotation to manage disk space. Log rotation involves periodically moving or compressing older log files, ensuring the log directory doesn't fill up.
6. Analyze and visualize logs: After the training completes, you can analyze and visualize the log files to gain insights into the training process. You can use tools like TensorFlow's TensorBoard or other log analysis libraries to parse and visualize the log data.

By following these steps, you can effectively handle log files in distributed TensorFlow training, making it easier to monitor and debug your training process.

How to redirect Estimator API's logging to a file in TensorFlow?

To redirect Estimator API's logging to a file in TensorFlow, you can follow these steps:

1. Import the logging module and set the logging level to the desired level. For example, to set the level to INFO, use:

1
2

import logging
logging.getLogger().setLevel(logging.INFO)

1. Create a file_handler object and set its filename to the desired file path. For example:

1

file_handler = logging.FileHandler('logs.txt')

1. Set the file_handler's logging level and format. You can specify the level to capture and the desired format. For example, to capture all logs and use a simple format displaying the level and message:

1
2

file_handler.setLevel(logging.INFO)
file_handler.setFormatter(logging.Formatter('%(levelname)s - %(message)s'))

1. Add the file_handler to the estimator's logger. You can access the logger through the estimator's model_dir property and call addHandler() to add the file_handler. For example:

1
2

estimator = tf.estimator.Estimator(model_fn=model_fn, model_dir='model/')
estimator.model_dir.addHandler(file_handler)

1. Now, all logs from the estimator API, including INFO, WARNING, ERROR, etc., will be redirected to the specified file.

Note: Ensure that the model_dir folder exists before running the code.
