Pillow Install Fails – Python 3.5.2

Hi everyone,

Pillow install fails

I ran into a bit of an issue trying to install Pillow on Raspbian with Python 3.5.2. The full error is below, but the solution was simply to install the following:

sudo apt-get install libjpeg8-dev
sudo pip3.5 install pillow

sudo pip3.5 install pillow
Collecting pillow

Check Tensorflow Version – Raspbian

Hey everyone,

Just a quick post on how to check the Tensorflow version on Raspbian with a one-liner (assumes Python 3.x):


python3 -c 'import tensorflow as tf; print(tf.__version__)'

Check out this Stackoverflow post for more info: https://stackoverflow.com/a/38549357/522859

AttributeError: ‘dict’ object has no attribute ‘iteritems’ – Python

Hey everyone,

Just running through object detection samples for Tensorflow and I encountered the following error:

Sample: https://github.com/GoogleCloudPlatform/tensorflow-object-detection-example

AttributeError: ‘dict’ object has no attribute ‘iteritems’

The issue seems to be that the sample hasn’t been made compatible with Python 3.x. Simply make the following change and it should work:


# Original
for cls, new_image in new_images.iteritems():

# Changed
for cls, new_image in new_images.items():

Converting proto files to .py on Windows – Tensorflow

Hey everyone,

Ran into a bit of an issue today with Tensorflow:

ImportError: cannot import name preprocessor_pb2

Turned out that I hadn’t run some of the installing steps. I needed to use protoc to convert the proto directory files:

protoc object_detection/protos/preprocessor_pb2.proto --python_out=.

This turned out to be a bit of a headache as well, but thankfully a github post explained it all pretty well:

Here are the steps I followed to install it for windows:
(Prerequisite, you must have python, pip and)

Choose a Python release from here and download: Link here
– Extract the tar.gzor zip
– Open a cmd and pip install the following: pillow, lxml, jupyter, matplotlib
– Copy the protoc.exe from the protoc folder (you don’t need to do all the CMake steps you might have stumbled upon, it worked for me without them too) and paste it into your protos folder in the object detection directory.
– Run the protoc for each of those protos like “protoc object_detection/protos/*.proto –python_out=.”. . Note that you might encounter a problem with the paths and there’s two ways around that: Either move the protoc.exe two folders down or do the noobish thing that I did – copy the protos and paste them into a new directory inside the protos folder ‘object_detection\protos’ so you would have a folder structure like’\object_detection\protos\object_detection\protos’ (If it looks stupid but it works, it’s not stupid eh?) Note that *.proto might also not work and you might have to do each of them individually
– You are done. :) Try to run something to see if you have any problems. You might have to install a manual version of numpyandscipy

TensorFlow – KeyError: “The name ‘import/input’ refers to an Operation not in the graph.

Hey everyone,

Just another small error I’ve run into while testing out Tensorflow’s label image example (Tensorflow/tensorflow/examples/image_retraining/label_image.py):

KeyError: "The name 'import/input' refers to an Operation not in the graph.

This one thankfully doesn’t seem to be my fault. In label_image.py change the following lines:

# Line 78-79
input_layer = "input"
output_layer = "InceptionV3/Predictions/Reshape_1"
 
# Change to this
input_layer = "Mul"
output_layer = "final_result"

Once that’s done just rerun your script and it should all work. Thanks to the following post for the solution: https://github.com/tensorflow/tensorflow/issues/12736

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:\Users\Chris-PC\Desktop\images-to-use\attempt2\tensorflow\examples\label_image\label_image.py", line 112, in <module>
    graph = load_graph(model_file)
  File "C:\Users\Chris-PC\Desktop\images-to-use\attempt2\tensorflow\examples\label_image\label_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

Rename all files in a directory with Sequential Numbers

Hey guys,

Just a batch script I came across that allows you to rename all files in a directory with sequential numbers. Really handy for things like tensorflow. All you need to do is create a batch file in the directory containing the following:

@echo off
setlocal EnableDelayedExpansion
set i=0
for %%a in (*.jpg) do (
    set /a i+=1
    ren "%%a" "!i!.new"
)
ren *.new *.jpg
