Issue when ussing pse_loader.py

[AlbertoGonzalezAbadia]

I do
events_file = file_name + '_td.dat'
video = PSEELoader(events_file)
I get
prophesee/src/io/psee_loader.py", line 57, in init
self._ev_count = (self._end - self._start) // self._ev_size
OverflowError: Python integer 244984720 out of bounds for uint8

What could it be?

Hello,
similar problem was reported by another customer but we were not able to go to the bottom of it. Maybe you can take a look and collect some help/information anyway: #43

I also met this problem (I just rename "src" to "prophesee_automotive_dataset_toolbox"):

from prophesee_automotive_dataset_toolbox.io.psee_loader import PSEELoader

def dat_to_npy(dat_fname: str):
    events = PSEELoader(dat_fname)
    print(events)



if __name__ == '__main__':
    dat_fname = '/vast/palmer/pi/panda/wf282/gen1/gen1/detection_dataset_duration_60s_ratio_1.0/train/17-04-13_12-15-24_61500000_121500000_td.dat'

    dat_to_npy(dat_fname)

Traceback (most recent call last):

this worked for me: self._ev_count = (self._end - self._start) // int(self._ev_size), probably newer versions tries to preserve uint8 for the division and therefore we get overflow error

Edit: just add this line self._ev_size = int(self._ev_size) and that will clear out any error
