valkyrie_simulation fails to load model in visualizer #6918

Closed hongkai-dai closed 7 years ago

hongkai-dai commented 7 years ago

When @edrumwri and I launch examples/valkyrie/valkyrie_simulation, we see an error in the drake_visualizer as

failed to resolve filename, unknown package: package://Valkyrie/urdf/model/meshes/pelvis/pelvis.dae
warning, cannot find file: package://Valkyrie/urdf/model/meshes/pelvis/pelvis.dae

    polyDataList, visInfo = Geometry.createPolyDataFromFiles(geom)
ValueError: need more than 0 values to unpack

But I can find that dae file in drake/examples/valkyrie/urdf/model/meshes/pelvis/pelvis.dae. Does that mean package://Valkyrie does not map to drake/examples/valkyrie in the drake visualizer?

Please post the exact commands you are running.

hongkai-dai commented 7 years ago

We did

$ bazel test //drake/examples/valkyrie:valkyrie_simulation

in one terminal. On another terminal, we launch the drake-visualizer as

$ ./bazel-bin/tools/drake_visualizer &

Then on the terminal where we launch the drake-visualizer, we see the error message above.

Other than bazel test vs bazel run (which likely does not make any difference), this seems like a duplicate of #6834. There were several problems identified there; TTBOMK none of the fixes have been PRd yet.

Thanks! I will close this issue, as it is a duplication of #6834
