Installation

[Yuanguo1994]

Hi, CsatiZoltan

When I install the software, some errors occur, showing in the picture. Does it mean the installation has failed?

Hi,

Only the installation of that specific Python package failed. The reason is that git is not installed on your system (as I see, you are working under Windows), therefore the command couldn't be executed. The PandasDataFrameGUI package is needed only for a small but useful functionality (to display grain statistics in a table). If you do not need that feature, you can leave it as it is. Otherwise, install git on your system. You can either install git only (e.g. through Anaconda: conda install -c conda-forge git), or by installing a GUI (which will install git itself).

Next time, please send the full error message as text and not as a screenshot so that it is easier for me to debug.

Hope it helps,
Zoltan

P.S.:
To see what to expect from the dependency that you failed to install, here are two screenshots for a microstructure. Basically, it enables you to filter grains by certain properties (area, diameter, etc), and also display the frequency distribution of those properties.

Yes, I know about this error. This is an error in the OpenCASCADE API. I will see what I can do.

Is there any other way to get the splinegon surface? It seems in the example, you get the splinegon surface.

The cause of the error is in version 0.17.3 of the pythonocc-core package. The reason I did not observe it before is that in my development environment, I installed pythonocc-core version 0.18.1 from sources, and that version works correctly. I don't recommend you to build pythonocc-core from sources as that would be complicated for Windows. Although version 0.18.x is available as a precompiled conda package, it has conflicts with some other packages that CristalX relies on. I have been planning for a long time (#19) to update pythonocc to a newer version, but that did not happen. I will do it soon because this functionality is a core feature of CristalX. In the meantime, as a quick fix, please comment out this line in the grains/cad.py file. You will get the splinegon surfaces (I checked it). Actually, the make_holes method is only necessary if your grains form non-simply-connected domains.

Thanks for your answer, now I can run through the whole example, and move to my microstructure segmentation. Really thanks for this, it helps me a lot!!!!
