Cannot find module "bark.core"

[Rx-SUN]

When debugging the python code "intersection.py", I followed the instruction from the tutorial and I got the error "no module named bark". I guess it is caused by wrong path. Then I used

import sys
sys.path.append("/home/myname/bark")

to add the path. But there is still error "no module named bark.core". This time I cannot find "bark.core".

This is what I added in launch.json file based on the tutorial https://bark-simulator.readthedocs.io/en/latest/debugging.html

{
                "name": "Python: Current File",
                "type": "python",
                "request": "launch",
                "program": "${file}",
                "console": "integratedTerminal",
                "env": {
                  "PYTHONPATH": "${workspaceFolder}/bazel-bin/bark/examples/intersection.runfiles/__main__/python:${workspaceFolder}/bazel-bin/bark/examples/intersection.runfiles/__main__"
                }
              }

Could you please tell me how to fix this?

(I have installed BARK correctly based on the website https://github.com/bark-simulator/bark/blob/master/docs/source/installation.md And the python file "intersection.py" runs well in terminal with commond "bazel run //bark/examples:merging")

My (educated) guess would be: bark.core is always moved to the actual build folder by bazel. This is done via the genrule command.

Possible solution: Add ${workspaceFolder}/bazel-bin/bark/ to the path as well. @juloberno might be able to help you here.

Hi, either you take Patrick's solution and add paths manually or in the meanwhile, we have a solution to set PYTHONPATH automatically. Here is a PR that adds this debugging feature to the merging example. Just hit F5 to start debugging while having the merging.py active in vs code.

We will also merge this into master when it is ready.

Problem should be resolved as it has been merged into the master branch.
