Shape:
         vid_tensor: (N, T, C, H, W). The values should lie in [0,
         255] for type uint8 or [0, 1] for type float.
add_audio(tag, snd_tensor, global_step=None, sample_rate=44100, walltime=None)
  Add audio data to summary.

  Parameters:
     * **tag** (*str*) -- Data identifier

     * **snd_tensor** (*torch.Tensor*) -- Sound data

     * **global_step** (*int*) -- Global step value to record

     * **sample_rate** (*int*) -- sample rate in Hz

     * **walltime** (*float*) -- Optional override default
       walltime (time.time()) seconds after epoch of event

  Shape:
     snd_tensor: (1, L). The values should lie between [-1, 1].

add_text(tag, text_string, global_step=None, walltime=None)
  Add text data to summary.

  Parameters:
     * **tag** (*str*) -- Data identifier

     * **text_string** (*str*) -- String to save

     * **global_step** (*int*) -- Global step value to record
