Hello Gi_T,
I followed the steps outlined in the both the Python Quickstart and in the Classify_picamera tutorials.
I noticed the download.sh, but I don’t think it is clearly called out in the Classify_picamera tutorial.
I ran
git clone https://github.com/tensorflow/examples --depth 1       (1)

and
cd examples/lite/examples/object_detection/raspberry_pi        (2)

As instructed and I saw
# The script takes an argument specifying where you want to save the model files
bash download.sh /tmp

I thought it was referring to (1), and talking about what that step was doing.
I do see on my Raspberry Pi where all the files have been copied to.
Did I not run the download.sh script?
Thank you,
Sean Worcester
