Could you send your log file to me and I will check it. My email [e-mail].

Hi, I have the same problem on Ubuntu 16.04. I can get log information using ulog_info, ulog_params, etc. but when I load my logs into pyFlightAnalysis, nothing happens. I just emailed you a couple of example logs. Thanks and let me know if you need anything else to look into this issue.

Kind regards,

I tried this simple test with one of my log files:

from pyulog.core import ULog
log_file_name = str(sys.argv[1])
log_data = ULog(log_file_name).data_list

Traceback (most recent call last):
  File "ulog_test.py", line 6, in <module>
    log_data = ULog(log_file_name).data_list
  File "/usr/local/lib/python2.7/dist-packages/pyulog/core.py", line 108, in __init__
    self._load_file(log_file, message_name_filter_list)
  File "/usr/local/lib/python2.7/dist-packages/pyulog/core.py", line 428, in _load_file
    self._read_file_header()
  File "/usr/local/lib/python2.7/dist-packages/pyulog/core.py", line 450, in _read_file_header
    raise Exception("Invalid file format (Failed to parse header)")
Exception: Invalid file format (Failed to parse header)

I am using pyulog v0.6.0 and my logs are generated by the current master of px4/Firmware nuttx_px4fmu-v2_default.cmake

Since this is a pyulog issue I created an issue in that repo also.

I checked the files you sent to me. It figure out that file log_370_2018-10-25-17-25-56.ulg was a bad file with all zero bytes, while the file log_368_2018-10-25-16-52-48.ulg is okay and can be parsed by pyulog. After using the second file, I found the problem and fixed it. So you can update to the newest version. 😄
