#108063 — Saving Consol outputs in a python script

Hello, I'm new to python and have a Question.

I'm running a c++ file with a python script like:

import os
import subprocess

subprocess.call(["~/caffe/build/examples/cpp_classification/classification", "deploy.prototxt", "this.caffemodel", "mean.binaryproto", "labels.txt", "Bild2.jpg"]) 

and it runes fine. On the console it gives me the output:

~/Desktop/Downloader/Sym+$ python Run_C.py 
---------- Prediction for Bild2.jpg ----------
0.9753 - "Class 1"
0.0247 - "Class 2"


What I need are the 2 values for the 2 classes saved in a variable in the .py script, so that I can write them into a text file.

Would be super nice if someone could help me!


have a nice day!

Steffen

You shouldn't use the call() convienence function, but instead create a
process using the Popen constructor, passing PIPE to stdout. Then use
communicate() to get the output.

This should get you started:

    process = subprocess.Popen(["commandline"], stdout=subprocess.PIPE)
    output, error = process.communicate()

Output will be a string, string has a splitlines method, etc.

pycaffe is a python interface to caffe.  You should look into it and 
probably use it.  Its functions will return python objects.  I suspect 
that is has a function that will return the result of calling the caffe 
classification function

Stackoverflow has question/answers tagged with 'caffe' and 'pycaffe'.
(There is also a caffe-users group on google groups.)
