I am unable to read some of my gt3x files. Here is one example case:

The gt3x file:
example_unpacking GTX3 exception.gt3x.zip

Console output of the exception while loading the above file:

i is outside payload bits = 126528
bitstring 0101
bitstring 010100000000
ERROR:root:Unpacking GTX3 exception: cannot reshape array of size 10544 into shape (30,3)
ERROR:root:Error rescaling log data: unsupported operand type(s) for *: 'NoneType' and 'float'

Hey @shaheen-syed - I'm not sure if you can help here, but I am getting some weird randomness for reading in the same file:
muschellij2/pygt3x#1

Hello,

When I try to read in gt3x files I get the error:

ValueError: cannot convert float NaN to integer

It's caused by line 184:

log_data[:] = np.NaN

I've tested on Python 3.10 and 3.8.8, for the later numpy version 1.20.3.

Code to snippet to reproduce:

import numpy as np
acc_data_type = np.int16
#acc_data_type = np.float #uncomment and this works

# create empty array for the acceleration data
log_data = np.empty((10, 3), dtype=acc_data_type)
log_data[:] = np.NaN

Hard coding to enabling scaling fixes the issue as it uses np.float which can be NaN. I'm guessing older versions of numpy allowed np.int16 to have NaN or silently converted to 0 but I haven't tested.

I am getting following exception for some of my gt3x files:

ERROR:root:Unpacking GTX3 exception: cannot reshape array of size 5120 into shape (40,3)
