AttributeError: 'NoneType' object has no attribute 'load_wav'```

when reaching this line: ```
waveform = self.speaker_encoder_ap.load_wav(wav_file, sr=self.speaker_encoder_ap.sample_rate)

self.speaker_encoder_ap is a NoneType for me, so it seems that self.speaker_encoder_ap wasn't initialized

the wav file im supplying is a 22050 mono file and it's path is correct

i'm running version 0.13

this works without a problem:

tts --text 'Hello world!'  --out_path out/out21.wav --model_name tts_models/en/vctk/sc-glow-tts --vocoder_name vocoder_models/en/vctk/hifigan_v2 --speaker_idx p245

Ok, the problem seems to exist because I don't supply and --encoder_config_path and --encoder_path
Unfortunately I haven't found out yet how to get this encoder

[54696d21]

ok, I figured it out

for everyone else having this problem: the encoder can be downloaded here: https://github.com/Edresson/SC-GlowTTS

tts --text 'Hello world!'  --out_path out/out_1.wav --model_name tts_models/en/vctk/sc-glow-tts --vocoder_name vocoder_models/en/vctk/hifigan_v2 --speaker_wav 28.wav --encoder_config_path /home/user/TTS-de_v1/0.13/encoder/drive-download-20210430T024321Z-001/config.json --encoder_path /home/user/TTS-de_v1/0.13/encoder/drive-download-20210430T024321Z-001/checkpoint.pth.tar

that issue is resolved for me, but can please the error be something like "no encoder path and encoder config specified" for this error

on further inspection it seems to me that i'm poking around at a part of this package that wasn't meant to be used already so I'm closing this issue :)

huge props to the authors for putting putting this implementation out in the same month the preprint is published
