Package not recognized or installed from pyinstaller

[Abh Hom]

I'm trying to create a UI for the deface package (https://pypi.org/project/deface/) in python using Tkinter as the basic UI elements. When I run the exe on my own computer which has all the packages installed (deface and ttkbootstrap) the program runs fine.

But whenever I run this same exe on a separate machine that does not have deface package manually installed, the program sends me an error saying 'deface' is not a recognized command.

For context, the deface package in python is a command line tool, so it runs entirely on the shell level rather than on a 'function from a script' level. Or at least this is my understanding.

I've tried to manually direct pyinstaller to the deface package using --add-data, and --CollectALL, and changing the spec file to make sure the 'deface' package is listed there but in all these methods, the same problem still occurs. At each point, and with every iteration of the pyinstaller exe, the failure point seems to be this line:

command = ["deface", file, "-t", str(current_threshold), "-o", outputfilename]

process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

First, I'm constructing the 'command' with all my required arguments for the 'deface' package. Then I'm passing this through to the command line using subprocess().

The error is still 'deface' is not recognized as a command, function etc. etc.

Is there something that I'm doing wrong? Is this error occurring because I'm sending this variable down to the command line using this exe file which is an incorrect method?

Thanks to anyone who gives feedback here. My current workaround is having to manually install python, deface, and ttkbootstrap beforehand and then my program runs just fine but I wanted a nice workaround this just because my potential users may not have technological expertise to install python and deface package by themselves. I wanted to give a nice 'point and click' method for my program and user interface.

this is tricky.

1) -- I can't tell from t he deface README, but *many* python command like programs can also be. run via the. python executable, e.g.

python -m deface

That is, the actual top level script is a python "Main" function somewhere that could be called directly. Ideally, this is how a Python command line tool is set up.

You could look at the build setup (e.g. pyproject.toml) and it might make it clear.

2) If not -- the problem is that deface, even if fully installed (which it may not be) in the Installer, that version isn't on the executable PATH. You may be able to explicitly set the path the executable.

I'd go down the road of (1) -- in any case, you need to figure out. how the top. level `deface` command gets installed, in order to figure out how to use it.

Good luck!

Abh,

 

Despite the fact that the documentation is light on documentation deface is actually usable as a python package as well as as a command line tool. If you look at the code in your_python_installation\ lib\site-packages\deface\deface.py or at https://github.com/ORB-HD/deface/blob/master/deface/deface.py and especially at how the main function works then you should be able to duplicate mains functionality but with the values coming from your GUI rather than from the call to parse_cli_args you should be able to avoid the call to subprocess.Popen (note that such calls, especially with shell=True are considered a security risk).

 

Once you have done that you should be able to use pyinstaller without any problems.

 

Hope that helps,

 

Steve

Too bad they didn't factor that a bit differently -- but as a hack, you may be able to set sys.argv, and then call parse_cli_args, if that's easier.
