Using iVABS without virtual environment

[Si1verBe11]

I'd like to use iVABS, but I can't not use virtual environment because of company's policy.
Instead of that, I just downloaded potable iVABS v0.11 and tried to run, but failed.

I already installed all required Python packages.

And set up PATH and PYTHONPATH

But if I type ivabs, I got this:

Is this a problem because I'm not using a virtual environment? Or is it something else?
If virtual environment is the problem, can I use iVABS without it?

This is caused by some changes in the numpy 2.0. This will be resolved in a future version. Right now the way to fix this is to install an earlier version: pip install numpy<2.0.

Here I attached the evals/eval.1/eval.log : eval.log

Can you try this command in evals/eval.1: prevabs -i cs\main_cs_set1.xml -vabs -ver 4.1 -h?

This is the results:

Two things,

1. The prevabs in the downloaded iVABS folder didn't work, so I downloaded PreVABS 1.5.1 separately and am using it. This was already explained above (https://github.com/orgs/wenbinyugroup/discussions/17#discussioncomment-10754255).
2. The current message says that there is no lamina named la_mat_1, which I have confirmed does not exist in the MaterialDB.xml included in PreVABS 1.5.1, nor in the MaterialDB.xml included in iVABS 0.11.

The examples are tested against the latest versions delivered in the ivabs package, so there could be some compatibility issues with older versions of prevabs. The issue of the latest prevabs (1.5.2) not running on your machine could be related with the mismatch of vabs dll. The code is compiled along with the library of vabs 4.0. If you are using vabs 4.1, then it may not work. I am working on updating prevabs to fix this.

The material and lamina data are stored in the main cross-section input file (opt_cs_box_lam/files/box.xml.tmp). The older version of prevabs looks for material data from an external database only. This is why it cannot find the lamina. The workaround is to copy the material and lamina data from the main input (box.xml.tmp) to the database (MaterialDB.xml).
