how to run rosinit in Matlab

Hi,

I just installed the ROS toolbox in Matlab, and type rosinit in the command window

But it shows that:

Launching ROS Core...

Invalid Python executable: ''. Use pyenv function to set the path to the Python executable and retry the command.

Could anyone help me on figuring out this issue?

Thank you so much

Hello Van,

Based on the error message, it looks like MATLAB cannot find an available python executable on your computer. rosinit requires you to install and setup Python2.7. Once you installed Python2.7 and run

>> pyenv('Version','2.7')

you should now be able to do rosinit if there is no other issues.

In case there is any, this doc page shows all ROS System Requirements that might be helpful.

Hope this helps.
