about loading VCTK_Corpus dataset？

[Joll123]

when I used librosa to load audio file of VCTK_Corpus, the following errors occurs. Has anyone encountered the same situation?
File "/anaconda3/envs/tf/lib/python3.6/site-packages/librosa/core/audio.py", line 112, in load
with audioread.audio_open(os.path.realpath(path)) as input_file:

File "/anaconda3/envs/tf/lib/python3.6/site-packages/audioread/init.py", line 116, in audio_open
raise NoBackendError()

audioread.exceptions.NoBackendError
