SLAM Workshop Notes:
 
>> If Step 2 of the Set Up does not work for you, alternatively use:

virtualenv myenv --python=python3
source ./myenv/bin/activate

Use 'deactivate' to exit the virtual environment.




>> A (non-optimal) solution to a conflict with a previously installed ROS:

From: https://stackoverflow.com/questions/43019951/after-install-ros-kinetic-cannot-import-opencv

"It looks like this problem is caused by ROS adding /opt/ros/kinetic/lib/python2.7/dist-packages to the python path. 
This actually happens when you activate ROS with the command source /opt/ros/kinetic/setup.bash. This line is often 
added at the end of your bashrc file, in /home/username/.bashrc.

A workaround is to remove this line from the bashrc file. This way the python3 opencv packages will be correctly used, 
and you can still run source /opt/ros/kinetic/setup.bash to use ROS. However, this does mean you cannot use ROS and 
python3 from the same environment."
