I installed Python32bit on my 64bit system and tried to install pyfmi library but I got several errors that could not be solved at the end. By the way, my TRNSYS version is 18, does the FMU tool work with the 18 version? If not, would you please let me know if there is any alternative way to speed up the co-simulation between Python and TRNSYS?</font></span></div><div class="gmail_default" style="color:rgb(11,83,148)"><span style="font-size:large"><font face="times new roman, serif">Thank you</font></span></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div><div style="text-align:right"><div style="text-align:left"><br></div><div style="text-align:left"><b><font color="#0000ff"><font size="1"> </font></font></b><br></div><br></div><font color="#0000ff"><font size="1"><br></font></font></div><div><font color="#0000ff"><font size="1"><br></font></font><div><div><font color="#0000ff"><font size="1"><br></font></font></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 2, 2023 at 9:47 AM Widl Edmund via TRNSYS-users <<a href="mailto:trnsys-users@lists.onebuilding.org">trnsys-users@lists.onebuilding.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg847451618903493332">

<p class="MsoNormal">Hi,<u></u><u></u></p>

<p class="MsoNormal">The generated FMU should work on Windows 10 without problems.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Most likely the issue is the compatibility of the generated FMU with the Python version you are using. Because TRNSYS 17 is a 32-bit application, the FMU’s binary is also a 32-bit. For this reason, you will also have to use a 32-bit version
of Python, otherwise the FMU import will not work.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am not sure if there is a pyfmi version available for 32-bit Python. An alternative would be to use an older release of Python (version 3.6) and package fmipp (version 1.4, see [1]) for importing and handling the FMU.<u></u><u></u></p>
