unclear how to run the texnn script

[murphyk]

Hi. I am not able to use your code in its current form (perhaps due to my ignorance). I did git clone https://github.com/rrtucci/texnn.git and then pip3 install -e . but this gives the error

ERROR: File "setup.py" or "setup.cfg" not found. Directory cannot be installed in editable mode: /Users/kpmurphy/github/texnn

I then tried running python3 asia/asia.py from the texnn directory but get the error

from texnn import *
ModuleNotFoundError: No module named 'texnn'

I did not include a setup file because it's such a simple program.

It requires no python packages besides the python3.

It requires several LaTex packages (see the global HEADER0 for a bare minimum of LaTex packages required)

All the python code is contained in 2 files, texnn.py and globals.py.

If it can't find the texnn.py file it means you have to cd to the directory in which the texnn.py file is located. I use PyCharm for python and TexStudio for LaTex and this is all done automatically.

If I copy 'asia.py' to the top level directory where texnn.py and globals.py live, it all works fine. But I wanted to avoid polluting the top level with example diagrams. I suppose PyCharm is adding some directory names to your path ?

[rrtucci]

I think so. My impression is that PyCharm does a cd to the top directory every time you run any python file. I always assume it is going to start looking at the top directory.

My colleague suggested this way to make things easier for others to use.

• Add __init__.py to texnn directory.
• Add setup.py file (see below) to texnn directory
• Run python setup.py develop
• Now anyone can run python asia/asia.py from texnn directory and it works.

Contents of setup.py:

NAME = 'texnn'
VERSION = '0.0.1'
if __name__ == '__main__':
    setuptools.setup(
        name=NAME,
        version=VERSION,
        packages=setuptools.find_namespace_packages('texnn'),
    )

However, your example scripts also write to the top level directory. So I made this tweak to asia.py so it writes to the directory that contains the example script.

import pathlib
dir = str(pathlib.Path(__file__).parent.resolve())
name = dir + "/asia"
# ... continues as before
