AttributeError: 'NoneType' object has no attribute 'keys'

[iklobato]

SO: Ubuntu 16.04
Docker: 2.5.0
Python3: 3.5.2
Python2 : 2.7.12
Tensorflow: 1.3.0 (intalled at both Python)

Made commands as root

./build.sh
./train.sh /<images/path>/tensorflow_image_classifier-master/pictures/training

Folders structure:

• tensorflow_image_classifier-master
  • src
  • pictures
    • test
    • training
      • cats
      • dogs

I honestly dont know why im getting this error

root@mw:~<path>/tensorflow_image_classifier-master# ./train.sh /<path>/tensorflow_image_classifier-master/pictures/training
Image directory '/tf_files/data' not found.
Traceback (most recent call last):

    class_count = len(image_lists.keys())
AttributeError: 'NoneType' object has no attribute 'keys'

EDIT: It was without the data folder

same here too

Same here, were you guys able to fix this?

[MathiasHaudgaard]

Getting the same error. Has this been fixed yet?

[MathiasHaudgaard]

@llSourcell do you know what causes this problem?

[rubenCodeforges]

Same here but looks like the repo is dead

You can use the latest tensorflow under ubuntu and python27, In fact, this is an official example of tensorflow https://github.com/tensorflow/hub/tree/master/examples/image_retraining, I have successfully built the official tutorial.

This happens because the folder hierarchy isn't correct. Instead of having your data in
/some/path/to/tensorflow_image_classifier-master/data then categories, you're missing the /data/ part. Your folder must be named 'data' and contain folder categories:
/some/path/to/classifier/data/class1
/some/path/to/classifier/data/class2

Once this is fixed you will get more errors, but not the same errors. Using the official tutorial is probably easier (EDIT: https://github.com/tensorflow/hub/tree/master/examples/image_retraining )

[csabag]

you have to give the full path of your classifier folder without the trailing /
E.g. /some/path/to/classifier

hello how to deal this bug?

hello how to deal this bug?

This is not a Bug. Its related to the full path including the /data folder.

Hey! Take care of the empty spaces between the directory names and it will work. Even the space between --image_directory=/your/path/to/training/folder/here
If space is encountered in any folder name leading to the training images directory, write it as :
for ex : folder name => "training images"
cd training\ images
This will work.
