4 years ago Same error here. Did you fix it?
ROS: [kinetic]
Gazebo: [7]
Ubuntu: [16.04]
-------------------------------------- [EDIT] --------------------------------------
I solved the problem using sudo pip2 install pyquaternion
cyanine-gi
Expected Behavior
I followed the installation in Tutorial#1 and it seems that my installation is set for python 2. I want to run the python files to control the drone.
Current Behavior
But when I run " python px4_mavros_run.py" it gives the following error:
from pyquaternion import Quaternion ImportError: No module named pyquaternion
I tried to install it with : " pip install pyquaternion ", and the terminal gives:
Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: pyquaternion in /home/srl/.local/lib/python3.6/site-packages (0.9.5) Requirement already satisfied: numpy in /usr/local/lib/python3.6/dist-packages (from pyquaternion) (1.17.4) WARNING: You are using pip version 20.1.1; however, version 20.2 is available. You should consider upgrading via the '/usr/bin/python3 -m pip install --upgrade pip' command.
It seems it is installed for python 3. So, I tried to run the script with "python3 px4_mavros_run.py" Do you think that I have to set my environment with python3 ?
