<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Hello dear Chris,<br>
<br>
Thanks for your kind help. You were right. I changed my default system python to python2.7 in my .bashrc file and now Rivet works properly.<br>
<br>
By the way, after I changed the default python, there were no difference for the pythonpath to include python2.7 and/or python3 directories or not. Rivet worked in any situation.<br>
<br>
Thanks for your time<br>

<div dir="ltr">Hi Mohammadreza,<br>
<div><br>
</div>
<div>I see what looks like a mixture of python2.7 and python3 lib directories in your PYTHONPATH. I don't know what the behavior of such a setup will be.</div>
<div><br>
</div>
<div>Rivet has not been tested (AFAIK) in a python3 environment: indeed some of the updates are simple (such as "print" -> "print()"), but I think we have to be careful about details of the cython configuration/compilation. It's possible that you're compiling
the cython bits with python2.7 libraries and then trying to run with the default system python (which is 3.5)...</div>
<div><br>
</div>
<div>I really suggest only having python2.7 directories in your PYTHONPATH, making a clean rivet installation, then seeing if it works as expected.<br>

Hello,<br>
<br>
I have both python 2.7 and python 3.5 installed on my computer. When I was installing the source file of Rivet, there where a few syntax errors which I corrected manually. For example the "print" command was without "()" and I added it and as you know this
is the difference between python2.7 and python3.X as you said. <br>
<br>
These are what you said:<br>
<br>
mohammad@Reza:~$ export PYTHONPATH<br>
<br>
mohammad@Reza:~$ echo $PYTHONPATH<br>
<br>
/usr/local/lib/python2.7/dist-<wbr>packages:/usr/local/lib/python<wbr>2.7/dist-packages:/home/mohamm<wbr>ad/root/lib:/usr/lib/python2.7<wbr>/site-packages:/usr/lib/python<wbr>3.5/site-packages:/usr/lib64/p<wbr>ython2.7/site-packages:/usr/li<wbr>b64/python3.5/site-packages:/<wbr>usr/local/include/python3.5m:/<wbr>usr/include/python2.7:/bin/pyt<wbr>hon:/usr/lib/python3/dist-pack<wbr>ages:/home/mohammad/Rivet-2.5.<wbr>3/bin:/usr/lib/python2.7/dist-<wbr>packages/rivet:/home/mohammad/<wbr>Rivet-2.5.3/pyext/rivet<br>
<br>
mohammad@Reza:~$ which python<br>
<br>
/home/mohammad/anaconda3/bin/p<wbr>ython<br>
<br>
I think anaconda uses python3.<br>

<div>There are still a number of things that could be going wrong. Could you tell us where your default python executable is and give us your PYTHONPATH? i.e.</div>

<div><font face="monospace, monospace">$ which python</font></div>

Dear Chris,<br>
<br>
Yes, I have set that. But again I have the same problem.<br>
Would you please think of it one more time?<br>
If you want more info about my system and the way I have installed the Rivet, we may have a meeting on Skype.<br>

Hello dear,<br>
<br>
I'm one of the students of SBU and I installed Rivet for my projects. When I want to run the program, I face this message: The rivet Python module could not be loaded: is your PYTHONPATH set correctly?<br>
<br>
I have studied your mailing list ( these links: <a href="https://www.hepforge.org/lists-archive/rivet/2015-September/006252.html" target="_blank">
https://www.hepforge.org/lists<wbr>-archive/rivet/2015-September/<wbr>006252.html</a>) and I couldn't solve the problem. I have both python 2.7 and python 3.5 installed on my Ubuntu Linux. I will be grateful if you help me.<br>
<br>
Thanks in advance<br>
