Launcher will not run after upgrade

Hi, I upgraded to deadline 10.1.16 and now my launcher does not launch. I ran monitor from the command line with -console switch and I get an error that there is no module named ‘cPickle’.

I am not sure how to fix that but wanted to know if there is a solution for this. Thank you.


“There is no cPickle in Python 3. Just import pickle . pickle will automatically use the C accelerator.”

Thanks but how do I get the deadline launcher to decide what modules it needs to load? In other words I don’t know how to change the deadline launcher loading procedure or if that’s even possible.

Below is the full error message from running launcher with the console switch.

Deadline Launcher will now exit

It is not entirely clear where the error was thrown - no stacktrace. Some module in Deadline that has not been properly upgraded to Python 3, it seems.

I bumping this thread in the hopes that someone at Thinkbox can give a hand here. Still a problem on this one machine and I have tried uninstalling and re-installing the client application as well as deleting stored settings but nothings seems to make this go away.

Please help. Thanks.

Could you try with one of the newer versions, e.g. 10.1.19? I feel that the python3 story is somewhat better with them.
