Hi everyone,

I couldn't get the python sample client to run. Is anyone else having the same issue?

Hello Mike,

The Python client has been discovered to contain an error that prevents it from working correctly.
We are tracking this issue and have plans to fix the sample for an upcoming build. For the time being, the version provided with the SDK remains broken.

Some users have made some minor changes to get the Python client to run. You can find a modified version of the Python client at: ...

Please note that this version has not been created or evaluated by OptiTrack, but that this seems to be working for other users. If more modification is required, you will need to compare the process, here, to that performed in the PacketClient sample.

If you would like more information on what was broken, one user seems to have discovered the issue is related to some unnecessary padding within the script.

I hope this helps.
