Hi all,
my name is Marcel and I am currently doing my Ph.D. in chemistry with focus on the crystallisation of cementious materials.
As I am totally new to evaluation of total scattering data I have tried reading some papers by Professor Billinge, Professor Proffen and Dr. Keen. In addition I have started the book "Underneath the Bragg Peaks".
All the materials take some time and thinking to get through but I think I am starting to get some kind of perspective on it.
Therefore I would like to start using pdfgui to refine some pdf data. Using the procedure with the py27 environment I unfortunately get the following error:

environment location: C:\University\Anaconda\envs\py27 added / updated specs: - diffpy.pdfgui[version='>=1.1.2'] The following NEW packages will be INSTALLED: blas pkgs/main/win-64::blas-1.0-mkl

A bit of searching using google shows that there are people who had similar issues when installing matplotlib for example. Unfortunately I am new to Python and don't have much experience regarding programming.
Therefore I would like to ask if anybody had a similar issue or might know a solution to this error and might be willing to share it.

Best regards and thanks in advance

Hi Marcel,

As you've noted, the error here seems to be with the qt dependency which isn't a PDFgui error, per se.

If you haven't worked through this yet, you could try installing the Qt packages alone and trying to determine what's causing the incompatibility in your environment (e.g as in https://python-qt-tutorial.readthedocs.io/en/latest/installing.html )

Hi Marcel,

we had exactly the same problem last week. For us indeed, installing all necessary packages one after another worked well. We were not able to find what exactly solved the problem, but after a while it worked.

Sorry, not very sophisticated, but seems like no one has found the reason for it yet.

Cheers

Anna

Hi Peter and Anna-Lena,

thank you very much for your support.

Unfortunately I haven't been able to run it. So far I tried uninstalling and reinstalling anaconda.
Additionally I have tried to get it to run by using a clean miniconda prompt.

So far nothing has worked unfortunately. The error remains the same.

I have encountered the error on three different windows computers running on windows 10 and 7 (2 laptops , 1 tower).

By chance I have installed it on a Mac where it somehow runs.

It seems to be related to the encoding as I have found that the error is connected to the active code page 65001.

Maybe it is related to the system language being German but as my informatic skills are very limited I have to gain more information.

I just wanted to give a small update.

Best

Marcel
