Get AttributeError: 'tuple' object has no attribute 'encode' from `match.py`

GabbySuwichaya commented 3 years ago

Could you please give some help to solve the following problem?

I have tested the matching with two images.

In /mnt/HDD4TB2/Disk-NIPS2020/H5_destination ...there are three files generated by detect.py:

- matches.h5
- keypoints.h5
- descriptors.h5

I have executed the following command:

python3 match.py /mnt/HDD4TB2/Disk-NIPS2020/H5_destination

However, I have received the following problem:

Hello, sorry for the late reply. Have you managed to solve your problem by now? If not, could you inspect what the offending name is (the ix variable in line 68)?

@jatentaki I am back ... I debuged with pdb.set_trace().... It shows that ix is "/mnt" .. ?
I guess that "/mnt"is a part of my path to the saved descriptor : /mnt/HDD4TB2/Disk-NIPS2020/H5_destination

Could you please help? What does this actually mean? And how to solve it ...?

Line 69    def __getitem__(self, ix):
Line 70    pdb.set_trace()
Line 71    descriptors = self.ds_file[ix][()]

But is it really ix == mnt that causes the exception or is it sometime later in the execution? Can you modify the code like this?

def __getitem__(self, ix):
    try:
        descriptors = self.ds_file[ix][()]
    except AttributeError:
        print(f'Offending attribute {ix=}')
        raise
    ...

but you're right that this mnt looks suspicious. In that case, I'd expect something wrong is going in detect.py. There are two relevant lines: splitting off the extension names would propagate the /mnt absolute prefix, but that prefix shouldn't be there in the first place because of listdir which normally returns file/directory names and not their paths.
