Problems running on the web interface

Asked by Isabel Pedraza

I want to use the web interface to do some basic calculations with my students. We have tried to submit the sample calculation:
p p > w+ j j , w+ > l+ vl
 and we are all getting the same message (using different computers) : sh: python3: command not found

I am not sure whether the web interface is still available to do such calculations.

"sh: python3: command not found"

This is a message that the python3 program was not found.
Do you have Python3 installed on the systems in question?
What happens if you issue the command "python3"?

For online running, the solution is a new platform:
Those old platform madgraph.uiuc and madgraph.phys are indeed not compatible with our latest version of the code/...

I do not have python3. I will try to install it and try again. I did not know we were running on the local computer. Thank you!

From the web interface you do not run it locally obviously. The issue that you see is that our webserver does not have python3 and therefore can not run mg5amc anymore.

That's why you need to use the new webinterface.
