predict.py dropping different errors

[JBloodless]

Hi! I'm trying to test prediction on wav and flac, but both of them drop me different errors: running wav file, I get

File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 98, in predict_class_label x_features = self.load_features(audio_file)
File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 135, in <module> print(model.predict_class_label(args.audio_file))
File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 87, in load_features
x_features = self.ch.transform(x0)
AttributeError: 'dict' object has no attribute 'transform'

and on flac file

Traceback (most recent call last): File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 135, in <module>
print(model.predict_class_label(args.audio_file))
File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 98, in predict_class_label
x_features = self.load_features(audio_file)
File "C:/dipl0m/ml-master/instrument-classification/predict.py", line 83, in load_features
x, fs = sf.read(audio_file)
File "C:\Users\jackb\AppData\Roaming\Python\Python36\site-packages\soundfile.py", line 374, in read
frames = f._prepare_read(start, stop, frames)
File "C:\Users\jackb\AppData\Roaming\Python\Python36\site-packages\soundfile.py", line 1447, in _prepare_read
self.seek(start, SEEK_SET)
File "C:\Users\jackb\AppData\Roaming\Python\Python36\site-packages\soundfile.py", line 870, in seek
_error_check(self._errorcode)
File "C:\Users\jackb\AppData\Roaming\Python\Python36\site-packages\soundfile.py", line 1455, in _error_check
raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Internal psf_fseek() failed.

I'm using Python 3.6.2 on Windows and the model from here. Could you help me to figure out the issue?

Hi, in the first problem it seems that tfr.PitchgramTransformer is not correctly deserialized from pickle (instead to dict). Probably because the JSON file contains serialized preprocessing.ChromagramTransformer which got changd to tfr.PitchgramTransformer. Try running the preprocessing again with up-to-date code. Second error is something to do with soundfile library. Try googing, I don't know. Or maybe just load the audio using librosa... Good luck!
