Zendar SDK Compile failed?

[daydreamer2023]

Hi!
I couldn't compile the SDK correctly.
Probably because of the protobuf, but I can't find a solution.

By the way, I can't import data_bp2 while /usr/lib/zendar is add to PYTHONPATH.
That's what i got under the folder '/usr/lib/zendar' :

thanks a lot!

Can you post the contents of /usr/lib/zendar?

[daydreamer2023]

The second picture is the contents of /use/lib/zendar in my conputer.

I found there also need a module named lidar_pb2.

ZendarSDK/python/viewer/image_viewer.py

Line 15 in bf2c304

import data_pb2, tracker_pb2, lidar_pb2

Maybe you could upload a file xxx.pro, and I can use protoc to generate the appropriate python files.

thanks!

[ghsyu]

They should be included in the zenapi dpkg, they were accidentally removed at one point, can you try pulling the newest main and trying again?

[daydreamer2023]

I have got the data.proto in the path : multimodal_variational_autoencoders_for_semi_supervised_learning_in_defense_of_product_of_experts-Supplementary Material.

But i haven't found the cues about lidar_pb2. Is it also contained in this repo?
