Hi all I’ll be using the DroneBlockly curriculum to teach Python programming this fall, and have run across a snag. I can use the Python coding just fine from my Windows machine, but am getting errors from the Raspberry Pi units. Due to a mixup with my district, that’s what my students will be using to code & fly with. Has anyone had luck programming/flying the drones from the Pis, and especially the code from damiafuentes (DJITelloPy)? Any assistance/advice appreciated! -David ---

Hi David, any chance you can share any error messages that you’re receiving on Pi? Have all the python dependencies installed correctly? Will you share the output of “pip list” please? ---

Dennis: So near as I can tell, all of the dependencies are correctly installed. I’m running Python 3.7.3 and updated the rest yesterday (and I’m about to burn a new SD card since this is driving me nutso). My PIP list is: (sorry, it doesn’t mean anything to me, but I’m sure you’re looking for something specific).

I reinstalled PiOS and installed Jupyter Notebook. It gave me some errors but runs. I was able to get the code running for the box lab (and the Tello Drone flew), so whatever that error actually was must have been related to the PiOS I was using. I tried using the simple.py in the DJITello from the DamienFuentes GitHub repository, but with no luck (and some errors). I’ve put all of the error messages in the following file: > **[Error messages installing Jupyter Notebook](https://docs.google.com/document/d/1d_-BO1aY-DigrN40knwAMbwH0NFsullTzDL4RrYMmBo/edit?usp=sharing)** > > Error message installing Jupyter Notebook pi@raspberrypi:~ $ sudo pip3 install jupyter WARNING: Value for scheme.platlib does not match. Please report this to distutils: /usr/local/lib/python3.7/dist-packages sysconfig:... It’s long. Sorry. Any assistance is appreciated. I have another fresh SD card ready to go. Note that I’m traveling on business through Saturday evening so will not be working on this again until Sunday/Monday. Thanks for all your help! -David ---

David, I took a different route that I wanted to share and just got this running. For starters I highly recommend doing this in a Python virtual environment. It keeps the dependencies clean and isolated from any global Python dependencies you may have. Pat covers that in the README file from the repo: [dbaldwin/DroneBlocks-DJITelloPy-Tutorial (github.com)](https://github.com/dbaldwin/DroneBlocks-DJITelloPy-Tutorial) The problem that I ran into is that opencv-contrib-python as specified in the requirements file wouldn’t install. I’m talking about the version here: [DroneBlocks-DJITelloPy-Tutorial/setup.py at master · dbaldwin/DroneBlocks-DJITelloPy-Tutorial (github.com)](https://github.com/dbaldwin/DroneBlocks-DJITelloPy-Tutorial/blob/master/setup.py#L14) [DroneBlocks-DJITelloPy-Tutorial/setup.py at master · dbaldwin/DroneBlocks-DJITelloPy-Tutorial (github.com)](https://github.com/dbaldwin/DroneBlocks-DJITelloPy-Tutorial/blob/master/setup.py#L14) So I went ahead and did the following. 1. After you initialize your virtual environment be sure to upgrade pip: ```auto python -m pip install pip wheel --upgrade ``` 1. The install the requirements: ```auto pip install -r requirements.txt ``` 1. It’s likely the opencv-contrib-python package won’t install. So I installed an older one: ```auto pip install opencv-contrib-python==3.4.14.51 ``` 1. The I had install some system libraries: ```auto sudo apt install libhdf5-103 sudo apt install libatlas-base-dev ``` 1. After that I was able to connect to Tello and run the takeoff and land example: [DroneBlocks-DJITelloPy-Tutorial/01\_takeoff-land.py at master · dbaldwin/DroneBlocks-DJITelloPy-Tutorial (github.com)](https://github.com/dbaldwin/DroneBlocks-DJITelloPy-Tutorial/blob/master/01_takeoff-land.py) Here is an output of my pip list from the virtual environment: Package Version Location * * * djitellopy2 2.3 DroneBlocks-DJITelloPy-Tutorial 1.0 /home/pi/Downloads/DroneBlocks-DJITelloPy-Tutorial imutils 0.5.4 numpy 1.21.1 opencv-contrib-python 3.4.14.51 opencv-python 4.5.3.56 pip 21.2.1 pkg\_resources 0.0.0 setuptools 40.8.0 wheel 0.36.2 In the near future I’ll talk to @pat.ryan about getting this fixed up so hopefully we can get it working out of the box. FYI this was done on RPi 3 Mobel B ---

That worked! (took me 2 tried because the SD card decided to die in the middle, but that’s a different issue). I appreciate the help, and any simplification you can provide. -David
