Hi,
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Good that you found a solution / hack . :-) I do think you should also make sure you have e.g. the Python mcrun, I believe this is what mcgui will be configured to use...</div>
<div class=""><br class="">
</div>
<div class="">In regard to the tool layer, this is almost identical in 2.7.1 and 3.1. And 3.1 can be worth investing a little time in e.g. because of the (NVIDIA) GPU support.</div>

Hi,

<div class=""><br class="">
</div>
<div class="">Hmm. Did you install the packages independently or using the “python metapackage”, i.e.</div>
<div class="">mcstas-suite-python (or mcstas-suite-python-ng in the case of 3.1)</div>
<div class=""><br class="">
</div>
<div class="">You may also try to directly install the python mcrun package</div>

Hi again,

<div class="">I am quite sure your user environment could affect the Python environment that e.g. mcgui “sees”.</div>
<div class=""><br class="">
</div>
<div class="">Your mcrun should in fact be sitting in the same directory where mcgui resides? But maybe you started it via a Desktop launcher?</div>

<div class="">Running (e.g.)</div>

<div class="">should give you a shell which knows about the Python mcrun?</div>
<div class=""><br class="">
</div>
<div class="">Alternatively call mcrun with the full path, this should be something like</div>
<div class="">/usr/share/mcstas/3.1/bin/mcrun </div>

<div class="">Which exact Linux Mint are you on? As I remember Mint is a Debian-variant - and was our Debian packages your method of installation? In this situation, the dependencies are assumed to be resolved using Python modules provided by the OS itself,

<div class="">Is your Mint python “in mint condition” ( ;-) ) or has it been enriched with pip-stuff installed at the system level? In the latter case it may be worth checking how the code behaves in a “pure” environment.</div>
