Bug summary
I'm getting a weird error locally on my Mac in Jupyter Notebook while trying to plot the graph with matplotlib.
The error is: AttributeError: module 'matplotlib' has no attribute 'pyplot' even though everything is imported correctly and code works on Google Colab.
Code for reproduction
import librosa
import librosa.display
import matplotlib.pyplot as plt
def plot_mel_spectrogram(wav_file_path):
y, sr = librosa.load(wav_file_path, sr=None)
S = librosa.feature.melspectrogram(y=y, sr=sr, n_mels=128)
log_S = librosa.power_to_db(S, ref=np.max)
plt.figure(figsize=(10, 4))
librosa.display.specshow(log_S, sr=sr, x_axis='time', y_axis='mel', cmap='coolwarm')
plt.title('Mel spectrogram')
plt.colorbar(format='%+02.0f dB')
plt.tight_layout()
plt.show()Actual outcome

Expected outcome
Plotted graph of mel spectrogram.
