Multiple Loggers
|
|
^^^^^^^^^^^^^^^^

logger2 = TestTubeLogger('tb_logs', name='my_model')
|
|
trainer = Trainer(logger=[logger1, logger2])
|
|
|
|
The loggers are available as a list anywhere except ``__init__`` in your
|
|
:class:`~pytorch_lightning.core.lightning.LightningModule`.
|
|
|

|
|
some_img = fake_image()
|
|
# Option 1
|
|
self.logger.experiment[0].add_image('generated_images', some_img, 0)
|
|
# Option 2
|
|
self.logger[0].experiment.add_image('generated_images', some_img, 0)
