Inherits From: Callback

Defined in tensorflow/python/keras/_impl/keras/callbacks.py.

Callback that streams epoch results to a csv file.

Supports all values that can be represented as a string, including 1D iterables such as np.ndarray.

Example:

csv_logger = CSVLogger('training.log')
model.fit(X_train, Y_train, callbacks=[csv_logger])

Arguments:

• filename: filename of the csv file, e.g. 'run/log.csv'.
