@nalindas9 Very sorry for the delay. I am not on here very often and I just saw your LinkedIn message. I believe the issue is, as you suspect, due to...

Ah yes, so there is a 90 degree rotation about the z-axis needed. I think the correct right-multiply matrix is: ``` [[0,0,1], [0,1,0], [-1,0,0]] ```

@Achllle Thanks for the suggestion! @benzben Very sorry for missing this! In general this is due to an import error, usually from broken dependency. You can see the stack trace...

@fbottarel Ok that is helpful. Do you have packaged traitlets installed?

Hey, Yes, and sorry for the delay. This issue was with the BerkeleyAutomation/visualization package. Please pull the latest from master for that repo.

This is a symptom of meshrender failing to build and install properly. Can you run: ``` cd /path/to/meshpy sh install_meshrender.sh ``` And post the output? I believe you have error...

Interesting that actually looks correct. Do you also have the other version of `meshrender` installed?: https://github.com/BerkeleyAutomation/meshrender Perhaps there is a name conflict.

You could try opening a Python interpreter and then examining the output of: ``` import meshpy print(meshpy.__file__) ``` Then see if there is a file `meshrender.so` in that directory

There is a probably some discrepancy between the Python and ipython installation. [This](https://github.com/ipython/ipython/issues/9896) seems to be relevant. Can you paste the output of: ``` which python which ipython ```

Please see above discussion. Can you paste the output of the following?: ``` python |>>> import test.database_test ```
