ValueError: vector::_M_default_append about pyhepmc HOT 7 CLOSED

Hi, thanks for trying this out. Unfortunately, we couldn't turn this project into the default Python API for HepMC3, they have their own independent Python bindings. Therefore, I cannot offer much support. I don't see something that you did wrong at first glance, it looks like a bug in our library.

tl;dr: I do not have time to support this library at the moment, so if you are doing serious work, I would recommend the official HepMC3 Python API for now.

Hi @HDembinski thank you very much for your reply.

I'm sadden to hear that, I was looking forward to having a python interface that wouldn't required installing HepMC...

All the best!

@romanovzky For my curiosity, did you find a solution or did you switch to the official HepMC3 Python bindings?

Hi @HDembinski neither to be honest. I was attempting this route to avoid having to use C++, but I just went on with it. I'm still very keen on a working python interface/wrapper, as almost all my work and workflow is strictly pythonic.

Also, I was bound to hepmc2 files, and the only hepmc3 seemed to have working python3 bindings?

Thanks for the heads up. I think you can read the HepMC2 format with HepMC3.

Now that you say that, I think I tried to use HepMC3 python bindings but had a similar issue. I can't recall the details as I was already not really convinced about the approach anymore. In any case, I did need to put together a FastJet routine, so using C++ was the obvious way. I just wanted to explore a python approach.

I cannot reproduce this in the latest version, so hopefully updating will fix things for you.
