Usage Examples
Try our integration out in a colab notebook (with video walkthrough below) or see our example repo for scripts, including a Fashion MNIST example and the W&B Dashboard it generates.
Configuring the WandbCallback
WandbCallbackThe
WandbCallback class supports a wide variety of logging configuration options: specifying a metric to monitor, tracking of weights and gradients, logging of predictions on training_data and validation_data, and more.Frequently Asked Questions
How do I use Keras multiprocessing with wandb?
Keras multiprocessing with wandb?If you're setting
use_multiprocessing=True and seeing an error like:1
Error('You must call wandb.init() before wandb.config.batch_size')
Copied!
then try this:
- 1.In the
Sequenceclass construction, add:wandb.init(group='...') - 2.In your main program, make sure you're using
if __name__ == "__main__":and then put the rest of your script logic inside that.
