I have been playing with a #selfdriving car for a while, and that is super exciting. From a #AI and #ML perspective it is small scale, but allows one to exploit all aspects of the tech stack and also appreciate the limitations of not only the software, but also the hardware.
With this You run a NN on a raspberry pi that uses TensorFlow, and Keras and runs inference on the edge. The pi doesn’t have enough power to train, so you need to do that on a beefier machine and then deploy the model back to run this.
Now, I didn’t have any issues in getting this running on Windows, but to get it on a Mac was a different story. The documentation is there that outlines all the steps, and even if you follow it to the T, it breaks right in the end.
When I tried to create a car, using a createcar command (this essentially creates the buckets, where you would save the training images, and the model, and the configuration of the car when you connect to it from your machine). The actual file paths would probably be different for you but, essentially it is the same thing.

pkg_resources.DistributionNotFound: The 'imageio<3.0,>=2.5' distribution was not found and is required by moviepy
The key here to focus is on the last lines on both of those blocks of code – the main thing causing the issue is MoviePy (see highlighted lines above).
MoviePy is a Python library for video editing: cutting, concatenations, title insertions, video compositing (a.k.a. non-linear editing), video processing, and creation of custom effects.
It seems like when you go through the steps – clone the repo, setup anaconda, install tensorflow and get the car configured – there is a mismatch in the MoviePy dependencies which it doesn’t like. The way to fix the issue is outlined below.
Skip MoviePy
MoviePy is something you don’t need to use right away but later when trying to make a movie (using the makemovie command – which allows you to create a movie file from the images in a Tub.); this is not essential. To do this, the easiest way is to remove (or my suggestion it to comment) out the moviepy dependency from the setup.py file.
This should be line 33 in the setup.py file that you will find in the same folder where you cloned the git repo. As an example the updated file is below, where the moviepy dependency is commented out (see highlighted). And once you save this and go about creating the car, it should work. Of course you cannot use the makemovie option later.

Once you have saved the setup.py file, you need to run the installation again with the following command and then run the create car command. Both of these are outlined below.
pip install -e . donkey createcar ~/mycar
Once you run these, then you should see the successful installation as shown by the output below. Note – your output might be a little different depending on the conda state of packages

And when I run the createcar, you can see it worked as expected. In my case creating the ‘mycar’ folder in my home directory. Of course you can choose this wherever you prefer.

It is interesting to see this is more stable on Windows, than on a Mac. Also, one last thing to leave you with – when I first ran the installation, the hint that someone was wrong was in the output, but I didn’t pay too much attention to it. See the red line highlighted in the output below.
Don’t know at this time on what the solution for moviepy is to get this sorted – luckily its not a big deal at the moment.
