How to remove the Y-axis labels, ticks and axis label in a plot created using librosa.display.specshow

Question

I am using this code to visualize the melspectogram and save the image

spec = librosa.feature.melspectrogram(y=y,sr=sr,n_mels=128 )
plt.figure(figsize=(12, 6))
spec = librosa.amplitude_to_db(spec, ref=np.max)
librosa.display.specshow(spec, sr=sr, y_coords=None,y_axis='log',fmax=20000)
plt.savefig('spectogram.png')

I am unable to remove the Y-axis labels, ticks, and the label of the axis and save them.

@Parth Shah I am getting this error: NameError: name 'ax' is not defined — Rahul Jaikrishna, Jul 11 '20 at 07:07
If you do not want to retrieve the axis `ax`, use `plt.yticks([])`. — Parth Shah, Jul 11 '20 at 07:09
It works! but the ticks are still visible and there still is a label "Hz". https://ibb.co/KmWL533 — Rahul Jaikrishna, Jul 11 '20 at 07:13
Do you not want the axis label? Do you not want the ticks? Edit the question with these details and I will post an answer. — Parth Shah, Jul 11 '20 at 07:14

Disable the axis all together with:

plt.axis('off')
