Jtop not working

[mlbach]

Thanks for building this useful tool. Unfortunately, jtop doesn't run on my Jetson. I get this error:

Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib/python3.5/threading.py", line 914, in _bootstrap_inner self.run() File "/etc/jetson_easy/jtop/jtoplib.py", line 69, in run self.jetsonstats = self.decode(tegrastats_data) File "/etc/jetson_easy/jtop/jtoplib.py", line 217, in decode lines = nvpmodel.split("\n") TypeError: a bytes-like object is required, not 'str'

Here's my output 'from jetson_release':

Hi @mlbach ,

thank you to open this issue. I didn't check in these days jtop on a Jetson TX2. Could you send me the output from:

sudo nvpmodel -q

Maybe the output is not the same from the Jetson AGX Xavier and Jetson Nano that I'm testing now.

Thanks for getting on this so quickly! For sudo nvpmodel -q

NV Power Mode: MAXN 0

For sudo nvpmodel -q --verbose

Hi @mlbach ,

I have updated the jetson_stats.

I suggest to uninstall your jetson_stats following:

cd jetson_stats
sudo ./install_jetson_stats.sh -uninstall

after that

sudo -H pip install jetson-stats

If your jtop have the same error, launch jtop in this mode:

sudo jtop --debug

after a while close and copy and paste here the file generate in the same folder you launch called jtop.log

Hi @mlbach ,

I found the error in jtop, was for python3 compare my test with python2.7.

The emulation of the error: https://travis-ci.org/rbonghi/jetson_stats/jobs/535332726#L253

Now the code is fixed and will be release a new version soon. ;-)
