module 'pygfunction.utilities' has no attribute 'segment_ratios' about ghedt HOT 17 CLOSED

from ghedt.

Can you type pip list and let me know which version of pygfunction you are running? We introduced segment_ratios in version 2.1 (https://github.com/MassimoCimmino/pygfunction/blob/master/CHANGELOG.md#version-210-2021-11-12).

You can run pip install -r requirements.txt to install all the required modules. It should update your pygfunction installation if you are running older than 2.1.

What IDE are you using? Is it accessing the same environment that you list there?

from ghedt.

I m using pycharm, and yes I have double checked, all the packages and correct versions are installed

from ghedt.

Could you go to Settings -> Project: ghedt -> Python Interpretor and share a screen shot of your interpreter where I can see that its pygfunction 2.1.0.

from ghedt.

That is strange. If you tag @MassimoCimmino's version 2.1.0 release, you can see that a pygfunction.utilities.segment_ratios() function does exist.

Have you looked at the pygfunction utilitites.py file in your environment to see if it has the segment_ratios() function. Perhaps try

pip uninstall pygfunction
pip install pygfunction==2.1.0

@mitchute have you ran into this issue?

from ghedt.

from ghedt.

Yes, I even tried to define it on the example itself

from ghedt.

If you look in C:\Users\davide\PychardProjects\pygfunction\G\venv_2 and find the pygfunction package, is the segment_ratios function inside of utilitites.py?

from ghedt.

On my system pygfunction is located in lib/python3.7/site-packages/pygfunction.

From there, when I open up utilities.py I can see that the segment_ratios function is defined. Is it in yours?

from ghedt.

No, it was not. I ve updated now, thanks.

from ghedt.

That is bizarre. Is the example file in ghedt running now?

from ghedt.

It has changed. I get this error message:
AssertionError: Method 'MIFT' is not an acceptable method.
Please provide one of the following inputs : ['detailed', 'similarities']

from ghedt.

Is that a ghedt or pygfunction issue?

from ghedt.

I think you need to replace all of the pygfunction files in that directory with version 2.1 files.

This is a pygfunction v2.0 error. There was a mistake in the reporting which got fixed in v2.1 (and 'equivalent' was also introduced). My guess is ghedt is trying to use the missing 'equivalent' solver.

from ghedt.

Yes, the example he is running is trying to use the default g-function calculation (equivalent with unequal segment lengths). Both introduced in pygfunction version 2.1.

@DavideDC9 The issue appears to be that your package manager is reporting that you have pygfunction==2.1 installed when the code contained in the package is actually pygfunction==2.0.

I'm going to close this issue because we have resolved what the original error was, and have found that the solution (for now) is for @DavideDC9 to replace his pygfunction installation with files from the v2.1.0 release. The heart of the issue is located outside of ghedt, perhaps in venv.
