wow, you already have one. I'm working on updating the disk image and will post a script here.. https://github.com/wroscoe/donkey/blob/wr/disk_img_script/install/make_pi_disk_img.sh

I was waiting for this device and got one immediately. Thanks for fast response.

hello again i have been getting this error "ImportError: numpy.core.multiarray failed to import", while using "donkey calibrate --channel 0" this line. i guess something wrong about numpy. i deleted and reinstalled numpy but no solution.

try numpy 1.8?

Answer of RexFuzzle works for me. thanks

Now calibrate is working, my motor and servo are calibrated. however new error while "python manage.py drive" :

tensorflow.python.framework.errors_impl.NotFoundError: /home/pi/env/lib/python3.5/site-packages/tensorflow/contrib/data/python/ops/../../_prefetching_ops.so: undefined symbol: _ZN6google8protobuf8internal26fixed_address_empty_stringB5cxx11E

It would be helpful to see where in donkey that was getting called. On my Pi B the drive script is working. Haven't tried autopilots yet with this TF 1.5.

tensorflow 1.4.1 works well. thanks

Hey guys completely new to Raspberry pi's and donkeycars and im glad to have seen this issue posted. I am having the same issue where the prebuilt zipped disk image is not booting with our Raspberry pi so it is blinking red. Power supply is goood, Wroscoe where can i find a newer/updated version of this file? Or how can i do this properly? I am a complete noob!! Thank you

[chinaq]

I am having the same issue.

here is the updated(for pi b+) disk image. It's is not fully tested yet though, so it might not work.

Just to say I was getting a similar but slightly different error:

tensorflow.python.framework.errors_impl.NotFoundError: /home/pi/env/lib/python3.5/site-packages/tensorflow/contrib/data/python/ops/../../_dataset_ops.so: undefined symbol: _ZN6google8protobuf8internal9ArenaImpl10AddCleanupEPvPFvS3_E

Following onukadri's suggestion of uninstalling tensorflow (I was on 1.7.0) and installing tesorflow 1.4.1 fixed it.

pip uninstall tensorflow
tf_file=tensorflow-1.4.1-cp35-none-linux_armv7l.whl
wget https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.4.1/${tf_file}
pip install ${tf_file}
rm ${tf_file}

I wasn't using an image, but instead installed by using this script as a guide:
https://github.com/wroscoe/donkey/blob/wr/disk_img_script/install/make_pi_disk_img.sh

I used that script too. Almost ready to test, we'll see if it works.... I installed tensorflow 1.7 I think, on raspbian stretch, so I don't know if that will work.

[meurig]

I’m on stretch lite if that helps

It worked! I successfully installed opencv 3.4.1, tensorflow 1.4.1, and donkey on raspbian stretch(rpi 3b).

[wroscoe]

I've taken opencv out of the image. We're going pure tensor! :) Here is the new install script... https://github.com/wroscoe/donkey/blob/dev/install/pi/install.sh
