rogerlew / undaqtools Goto Github PK

Hi Roger,

Thank you for your awesome package. I am trying to read in a DAQ file since the automation updates to the simulator. But some, not all, files produce an error. I am not sure if it is because something is outdated in undaqTools. Could you please have a look? Thank you.

DAQ file

I have 2 DAQ files that I am trying to read in. The WithTraffic file is successfully read in, but the NoTraffic file produces the error below. You can download both files here

Code and Error

I have the following script that I run with python 02_convert_daq_files_to_hdf5.py. But it produces the error below.

# Changing directory to the folder where DAQ files reside ----------------------------
import os
os.chdir("C:\\Users\\HP\\Desktop\\driving_sim\\data\\daq")



# Getting the names of all DAQ files
import glob
ctnames = glob.glob('*.daq')
#print(ctnames)




# Importing and using undaq tools to convert all DAQ files to HDF5 format
# import sys

from undaqTools import Daq
for n in ctnames:
  daq = Daq()
  x = daq.read(n)
  daq.write_hd5(x)
  # print(type(x))

Traceback (most recent call last):
File "02_convert_daq_files_to_hdf5.py", line 30, in
x = daq.read(n)

I am trying to make your awesome tool undaqTools accessible to R language users by wrapping Daq(). However, python 2 support is going to end in R (via reticulate package). Do you have any plans to release the package for python 3?
