Tensorflow – No such file or directory

Hey guys,

Just a quick post on how to resolve an error I came across while testing out tensorflow: 

Traceback (most recent call last):
  File "C:UsersChris-PCDesktopimages-to-useattempt2tensorflowexampleslabel_imagelabel_image.py", line 112, in 
    graph = load_graph(model_file)
  File "C:UsersChris-PCDesktopimages-to-useattempt2tensorflowexampleslabel_imagelabel_image.py", line 30, in load_graph
    with open(model_file, "rb") as f:
FileNotFoundError: [Errno 2] No such file or directory: 'tensorflow/examples/label_image/data/inception_v3_2016_08_28_frozen.pb'

All you need to do is download the following file and place it in the directory in the error message: https://storage.googleapis.com/download.tensorflow.org/models/inception_v3_2016_08_28_frozen.pb.tar.gz

Start a Script on Startup – Raspberry Pi

Hey guys,

Just thought I’d leave a couple of links to some guides I came across for setting up boot scripts on a raspberry pi.

Quick guide on how to get them running: http://www.instructables.com/id/Raspberry-Pi-Launch-Python-script-on-startup/

How to delay the boot process until the network is available: https://raspberrypi.stackexchange.com/a/45774

Exit Raspberry Pi Camera Preview

Hey everyone,

I ran into a bit of a weird issue with a raspberry pi camera preview today. After starting the preview I hit an uncaught exception which meant that exitPreview was never called.

To get around this use the terminal hotkey and kill the python process. Note that while you won’t be able to see the terminal, it will be running in the background.
