I'm facing issue with tensorboard loading in Google Colab. I tried to uninstall and then install it again but no sucess. i'm sharing the code and the error.

!pip install tensorboard

%load_ext tensorboard

log_folder = 'log1'

callbacks = TensorBoard(log_dir= log_folder, histogram_freq= 1)

model.fit(train_X, train_y, validation_data = (test_X, test_y),callbacks= callbacks,verbose= 0, epochs = 20)

%tensorboard --logdir = '/content/log1'  I tried withour quotes as well i.e /content/log1
