dexnet.api:Failed to import DexNetVisualizer3D #20

Closed red-eyed-tree-frog closed 6 years ago

red-eyed-tree-frog commented 6 years ago

This error is produced every time the cli is launched.

WARNING:dexnet.api:Failed to import DexNetVisualizer3D, visualization methods will be unavailable

After numerous installs and investigations there do not appear to be any dependency issues. The kinect/libfreenect packages are not yet installed but I do not think that would be causing this.

Could there be some bad file-paths in the source code? Has this issue been encountered before?

red-eyed-tree-frog commented 6 years ago

Solved by changing line 50 in dex-net/api.py

from:

try: from dexnet.visualization import DexNetVisualizer3D as vis except: logger.warning('Failed to import DexNetVisualizer3D, visualization methods will be unavailable')

to:

from dexnet.visualization.visualizer3d import DexNetVisualizer3D as vis
