How can I process OPUS format with Librosa?

Question

I am trying to generate spectrograms by using Librosa. When I was working with the .wav format file it was working fine. But I changed the format to OPUS audio codec and tried to run the same file, it give me below error.

X, sample_rate = librosa.load('TESS emotion datasets opus/OAF_Fear/OAF_beg_fear.opus', res_type='kaiser_fast', duration = 2.5, sr = 22050*2, offset = 0.5)

Error generated:

NoBackendError: 

I tried to install ffmpeg and gstreamer as suggested by some previous answers and github page of Librosa. But it didn't solve the problem.

On the contrary, this audio format works well when I run the same code in Google Colab.

What can be the reason of this error? How to solve it?
