How do I use the model Inception.tgz in TensorFlow?

Question

I just downloaded the inception.tgz file from tensorflow.org at http://download.tensorflow.org/models/image/imagenet/inception-2015-12-05.tgz . But, I do not know where I should extract this.

Also, when I used the models/image/imagenet/classify_image.py script to get the model, the model was not saved after a reboot, so I had to download it again via the same script. I need to use it at times I am not connected to the Internet, so downloading the model everytime I need to classify is not ideal for me. How can I persist the model once and for all?

Also, how can I use the .tgz inception model?

Answer 1

I cannot make a comment to your Question since I do not have enough credits yet. So let me give you a generic answer.

1. The inception-2015-12-05.tgz file you mentioned contains two files which you require:

   a) imagenet_comp_graph_label_strings.txt

   b) tensorflow_inception_graph.pb

There is a license file that you won't require as well. These two files will let you make predictions on images.

2. The part where you mentioned the model was not saved after a reboot, so I had to download it again via the same script intrigues me. I have never come across such an issue. Try this now:

   • Create a folder in a location of your choice. Say ~/Documents .
   • When you run the python script classify_image.py use the --model_dir flag to redirect the model file directory to ~/Documents . This will essentially download and extract the necessary files to the specified location and you can use the same location in --model_dir flag ever since.

Take a look at this:

The model was not downloaded the second time. Hope this helps.

默认情况下，映像模型会下载到/ tmp / imagenet，但您可以通过将--model_dir命令行参数传递给--model_dir来设置自己的文件夹： https ： //github.com/tensorflow/tensorflow/blob/master /tensorflow/models/image/imagenet/classify_image.py#L56

Answer 3

because it is saved in a temp directory, everytime you shut the machine down, it is removed. try saving the file to a directory using the --model_dir parameter.
