I got some problems when train network

[Wangs121]

Hello, When I run 'Learn to Drive.ipynb' , In Train non-recurrent network part of :
`tb_counter = max([int(num) for num in os.listdir('../logs/')]) + 1
tensorboard = TensorBoard(log_dir='../logs/' + str(tb_counter), histogram_freq=0, write_graph=True, write_images=False)

minimizer = SGD(lr=0.0001)

#model.compile(loss=custom_loss, optimizer=minimizer)
model.compile(loss=custom_loss, optimizer='adam')

model.fit_generator(generator = gen_train.get_gen(),
steps_per_epoch = num_train,
epochs = 3,
verbose = 1,
validation_data = gen_valid.get_gen(),
validation_steps = num_valid,
callbacks = [early_stop, checkpoint, tensorboard],
max_q_size = 3)`
it occurred an withFileNotFoundError, can't find ../logs/ folder, but when I create a folder named logs, another error occurred. Your generous help means a lot to me. Thank you.
