ValueError: If printing histograms, validation_data must be provided, and cannot be a generator.

今天在用tensorboard的时候遇见了下面的错误：

Traceback (most recent call last): File "vgg16_finetune.py", line 368, in callbacks=[tbCallBack,csvlog,checkpointer]) File "/home/eric/anaconda3/lib/python3.6/site-packages/keras/legacy/interfaces.py", line 91, in wrapper return func(*args, **kwargs) File "/home/eric/anaconda3/lib/python3.6/site-packages/keras/engine/training.py", line 2280, in fit_generator callbacks.on_epoch_end(epoch, epoch_logs) File "/home/eric/anaconda3/lib/python3.6/site-packages/keras/callbacks.py", line 77, in on_epoch_end callback.on_epoch_end(epoch, logs) File "/home/eric/anaconda3/lib/python3.6/site-packages/keras/callbacks.py", line 820, in on_epoch_end raise ValueError('If printing histograms, validation_data must be 'ValueError: If printing histograms, validation_data must be provided, and cannot be a generator.

我的tensorboard的代码为：

tbCallBack = TensorBoard(log_dir=TENSORBOARD_PATH, histogram_freq=10, write_graph=True, write_images=True)#* tensorboard --logdir path_to_current_dir/Graph --port 8080 print("tensorboard --logdir {} --port 8080".format(TENSORBOARD_PATH))

解决办法

直接把histogram置为0，就行了，我的环境是keras2.1.4, ubuntu 16.04

tbCallBack = TensorBoard(log_dir=TENSORBOARD_PATH, histogram_freq=0, write_graph=True, write_images=True)#* tensorboard --logdir path_to_current_dir/Graph --port 8080 print("tensorboard --logdir {} --port 8080".format(TENSORBOARD_PATH))
