IndexError: list index out of range

[LINUX3932]

About 70% of my files work fine.

However, the remaining fingerprints give an IndexError when attempting to store. Others store okay but give an error when a match exists (If I don't store a fingerprint for these particular files it works correctly, returning '[ ]').

store error example: Traceback (most recent call last): File "go_storedb.py", line 5, in fp_r.create() File "/qfp/fingerprint.py", line 58, in create self.strongest = n_strongest(spectrogram, quads, q) File "/qfp/utils.py", line 66, in n_strongest partitions = _find_partitions(quads) File "/qfp/utils.py", line 80, in _find_partitions last_x = quads[-1].A.x IndexError: list index out of range

query error example: Traceback (most recent call last): File "go_querydb.py", line 9, in db.query(fp_q) File "/qfp/db.py", line 153, in query fp.match_candidates = self._find_match_candidates(fp) File "/qfp/db.py", line 177, in _find_match_candidates for k, v in binned.items() if len(v[list(v.keys())[0]]) >= 4} File "/qfp/db.py", line 177, in for k, v in binned.items() if len(v[list(v.keys())[0]]) >= 4} IndexError: list index out of range

I have checked the wav and mp3 files for any errors and they're fine.

I have same problem. Did you find any solution for this error?

Also having this issue. I'm starting to become familiar with the codebase and am planning to read the paper, so I hopefully will be able to fix this in my fork: https://github.com/SuperSonicHub1/qfp

The following lines of code can solve the problem

        result = {}
        for k, v in binned.items():
            if k and v and v.keys() and len(v[list(v.keys())[0]]) >= 4:
                results[k] = self._scales(v)
