Test Error in Python 3.10

[pravins02]

          Greetings @fangohr 

I tried installing Ubermag on my machine following the instructions from the video and the link shared above and encountered the same error as displayed above.

Please advise me on how to proceed in this aspect.

Thank you

Hi @pravins02, this seems to be a problem with your Anaconda installation on Windows, nothing related to Ubermag.

This stackoverflow thread could maybe help: https://stackoverflow.com/questions/54876404/unable-to-import-sqlite3-using-anaconda-python/55642416#55642416

Thank you for the reply @lang-m but, I uninstalled everything and tried again installing by following the procedures, and its still showing me the same results. Can you please look into it?

Thank you in advance.

Dear @pravins02, your issue is likely to do with anaconda on your computer, not Ubermag. We cannot reproduce it. @lang-m has pointed to an stackoverflow issues where somebody else had the same problem, and a solution is reported there. Try to follow that - that's the best advice we can give from here.

You could also try a more recent version of anaconda, try a different user account on your computer, try it on a different computer, etc. to try to figure out what the problem is. We are not very skilled with MS Windows.

Thank you, @lang-m and @fangohr for your suggestions.

I tried that and now there is no DLL error. However, when I tried running the program I found the attribute error. As I am not much familiar with python, I am learning that also.

Here is the error which I have found after the test.

Thank you in Advance

Hi @pravins02 based on the screenshot I cannot say why the tests are failing. Could you please share the whole test log with us? You can obtain it by running

python -c "import ubermag; ubermag.test()" > ubermag-test-output.txt

in the Anaconda Prompt. This will create a new file ubermag-test-output.txt (note: it would overwrite an existing file with the same name!) that you can upload here.

Hi @lang-m

As per your suggestion, I am hereby attaching the test log.

ubermag-test-output.txt

Let me know what needs to be done after this to remove this error.

Thank you

Hi @pravins02

Thank you for sharing the test file.

Three of the errors (test_read_write_vtk and both test_ovf2vtk) are related to some changes in the dependencies. However, these are only relevant for you, if you need vtk export capabilities (which would not be done internally). You can ignore those unless you use and need field.write("<filename>.vtk"). ~If that is the case you can try to install an older version of numpy (conda install -c conda-forge numpy=1.20). That should fix these tests.~ Edit: I assume that you have an old version of vtk. After creating the list of packages (see below), you could update vtk. That should fix the problem.

The last error (test_dirname) is related to some permission difficulties when running OOMMF on Windows. This should not affect your actual simulations, only causes the test to fail.

So as a conclusion, the failing tests should not be a major concern for you and you should be able to run simulations with Ubermag without any problems.

To help us resolve the dependency problem related to vtk, could you please upload a full list of your installed packages, which you can obtain by running

conda list > ubermag-packages-list.txt

in the Anaconda Prompt.

Hi @lang-m, sorry for the delay.

I have tried that and I was getting the Attribute error in the simulation which was earlier discussed in "_AttributeError: Object has no attribute k3dvector. #87".

I did follow the solution there and my simulation started to work.

Thank you for the prompt response and guidance. However, I am attaching my package list here as suggested by you.

ubermag-packages-list.txt

Thank you so much

[lang-m]

Thanks at @pravins02 for sharing the package list.

Internal note: vtk the issue seems to result from too old vtk + too new numpy. I have updated the minimum required vtk version: ubermag/discretisedfield#375

Closing as resolved.
