Issue with ulog analysis.ipynb

[AlexandreBorowczyk]

Hi I'm running in the following issue will trying the example.

    365 
    366     tmp_dir = tempfile.mkdtemp()
--> 367     pyulog.ulog2csv.convert_ulog2csv(
    368         ulog_filename, messages, tmp_dir, ',')
    369     log_name = os.path.splitext(os.path.basename(ulog_filename))[0]

AttributeError: module 'pyulog' has no attribute 'ulog2csv'

Same here. Tried also to run example outside anaconda with arch linux's python 3.6.2 (and px4tools + other deps installed via pip), but:

`px4tools.estimator_analysis(d_concat_computed)
File "/usr/lib/python3.6/site-packages/px4tools/ulog.py", line 404, in estimator_analysis
df.t_vehicle_attitude_0__f_roll_error.mean()),
File "/usr/lib/python3.6/site-packages/pandas/core/generic.py", line 3081, in getattr
return object.getattribute(self, name)

AttributeError: 'DataFrame' object has no attribute 't_vehicle_attitude_0__f_roll_error'
`
Looks like some incompatibility with new PX4 firmware. At least review on https://review.px4.io/ is working.

@AlexandreBorowczyk Any solution to the ttributeError: module 'pyulog' has no attribute 'ulog2csv' issue?

I am getting the same error.

[AlexandreBorowczyk]

nothing new, I'm using https://github.com/PX4/flight_review now.

Ok. I just found a way to get rid of that error. I built px4tools from source and uninstalled the versions that were installed by either conda or pip

pip uninstall px4tools

and while being inside conda environment:

conda uninstall px4tools

install px4tools from source while being inside conda environment:

. conda_env
git clone https://github.com/dronecrew/px4tools.git
cd px4tools
python setup.py build install

Hope this helps.

As the error suggests the issue comes from pyulog. I just found a way to get rid of it. Uninstall pyulog and reinstall from source.

pip uninstall pyulog

install pyulog from source

. conda_env
git clone https://github.com/PX4/pyulog.git
cd pyulog
python setup.py build install

The solution is almost similar to @mzahana but its enough to build only pyulog from the source! Hope it helps!

Thank you very much, guys!

I just did the same thing but without . conda_env (which I don't use) and I still have the same error. Any idea what's wrong? How to build it on Windows machine without conda?
