How to use pip3 without sudo privileges

-

In my case, there are several python3.x version installed in my system before, and I had to type python3.x and sudo pip3 for developing the code every time, which disturbed me. 

Here are the methods I tried to solve this problem. Now I am able to type only the python3 command for the newest python3.8 use and pip3 for installing modules without root privileges.

  • python3.x ... -> python3 ...
  • sudo pip3.x install ... -> pip3 install / python3 -m pip install ... 


1. Install pip3 locally under /home/$USER/.local/bin/.

$ wget https://bootstrap.pypa.io/get-pip.py

$ python3 get-pip.py --user

2. Edit ~/.bashrc

$ export PATH=$PATH:~/.local/bin

$ export PYTHONPATH=$PYTHONPATH:/usr/lib/python3.8/dist-packages

$ source ~/.bashrc

3. Delete redundant pip path or error: ModuleNotFoundError: No module named 'pip._vendor.retrying' will be reported.

$ sudo rm -r /usr/lib/python3/dist-packages/pip


Check:

$ python3 --version


* Difference between /usr/local and /usr/.local

/usr/local is a place where software usable by all users can be installed by an administrator.
~/.local/bin is a place where a user can install software for their own use.

Tuing PID parameters in QGroundcontrol (2)

Based on tips for tuning PX4 PID parameters written in my previous post [1] or even using the default values directly, you will be able to fly your vehicle freely in manual or stabilized flight mode.   However, if you are using an unique vehicle (usually assembly by yourself and only equipped with sensors you desire) and struggling for finding the best PID parameters for your applications. I think following 8 tips will help you to get ideal PID parameters.  This is the vehicle I made based on LHI QAV250 fiber frame, with TX2, high-speed camera, etc.[2]  Tip1:  Tuning order: Rate controller -> attitude controller -> position controller The PX4 controllers are layered [3], which means a higher-level controller passes its results to a lower-level controller. Thus the PID tuning needs to be done from lowest-level controller to highest-level controller. Tip2:  Check if  PWM_MIN  is set correctly. Remove propellers Arm the vehic...

1. Download the pixhawk support package [1] 2. Open MATLAB R2017b and navigate to the file location. 3. Click "PX4PSP_v3_0_4_351_R2017b" and install it 4. Create a folder for firmware download path (ex: D/PX4) 5. Setting bash environment for windows 10 [2]  (1) Active "Windows subsystem for linux" (2) Download and install Ubuntu (3) Using the terminal like in Ubuntu environment ex: 6. Install all necessary toolchain with " windows_bash_nuttx.sh " [3] or using Cygwin Toolchian [4] or [5] (python27 would show in following folder) 7. Key in command " PixhawkPSP(' D:\PX4 ') " in the Matlab 8. Make sure windows 10 bash and python path are correct => Validate paths 9. Download firmware to the folder we specify before and then validate firmware. 10. Selecting cmake configuration [6] 11. Build firmware *Error: make command not found   Solution: [7] T...
