问题描述

Firstly i'm new to python environment.

I installed PIP in mac using terminal and the python version is 2.7.16. I want to install and use Simple Image annatator(https://github.com/sgp715/simple_image_annotator).

I install flask(pip install flask) and i did cd into the cloned folder if simple image annotator. For reference please see the github repo for installation steps.

Than after i don't know what to do to use this library if i run this command(python app.py /images/directory) it gives No files.

How can i install and use the simple image annotator in mac can somebody please tell me the setup process steps.

working with python libraries is entirely new to me. Thanks in advance.

BELOW IS EDITED QUESTION FOR MORE EXPLANATION:

I installed flask and moved to the cloned folder please see the terminal commands as shown in screenshot.

Next remaining installation steps are:

  1. start the app

  2. $ python app.py /images/directory

you can also specify the file you would like the annotations output to (out.csv is the default)

  1. $ python app.py /images/directory --out test.csv

  2. open http://127.0.0.1:5000/tagger in your browser only tested on Chrome

I don't know how to execute remaining steps. images are available in downloads/images folder in my mac.
