TypeError: object of type 'Tensor' has no len()

Question

Hi am trying to get the length of files. am using tf version 1.14.0 and keras 2.2.4. But the below code is written in 2.6 version. Am getting error:

TypeError: object of type 'Tensor' has no len()

Can anyone help to change the code for tf==1.14.0?

My datasets are audio files around 3000 files.

**filenames = tf.io.gfile.glob(str(data_dir) + '/*/*')
filenames = tf.random.shuffle(filenames)
num_samples = len(filenames)
print('Number of total examples:', num_samples)
print('Number of examples per label:',
      len(tf.io.gfile.listdir(str(data_dir/commands[0]))))
print('Example file tensor:', filenames[0])**

Answer 1

len() might not be supported for a Tensor for Tensorflow version 1.14.0. Use .shape instead.

num_samples = filenames.shape[0].
