Useless

[luisivanhr]

The implementation of this library is utter shit. I have been trying for days to install this package and it keeps throwing so many errors with SWIG, C++ compilers and missing development headers. So sad that for such an awesome set of tools the implementation is so poor and outdated. Could we get a decent build of this library anytime soon?

I went as far as trying to install tick on fresh installation of ubuntu 24.04.1 virtual machine. Still no dice, run in to the same issues.

This library is not in a great shape for two reasons:

1. It has been 5 years now since I have not worked with Hawkes processes, hence a much much smaller involvement. Since then @PhilipDeegan has held the project together, maintaining it in the best possible state, and we should be grateful to him. You can give him a hand by following this thread: Updated wheel release mechanism #511
2. This library had been written to maximize its performances and we had too much disregarded the maintainability aspects (hence all the SWIG issues), on the long run that was a mistake.

[PhilipDeegan]

if you look at this branch and at the github workflow files, you should be able to build this yourself

https://github.com/PhilipDeegan/tick/blob/releases/.github/workflows/build_nix.yml#L40-L66

The reason why this PR is not merged, is that there are test failures which I am not equipped to fix, otherwise things should work for you

[Stuchbery]

I didn't delve into fixing the build files myself but I did eventually get the library to run in a VM using ubuntu-18.04.6 (bionic beaver) with swig and python3.6.

[PhilipDeegan]

@Stuchbery that's one way of doing it, but python3.6 is EOL so you'll likely have other issues too

@PhilipDeegan Hey man, first off thanks for maintaining this in your branch. I have a quick question; I can compile everything fine with no errors but when I try to import a package I get the following error:

 File ~/opt/anaconda3/envs/mainenv/lib/python3.11/site-packages/tick-0.7.0.2-py3.11-macosx-11.1-arm64.egg/tick/tick_cpp/__init__.py:1
    from .tick_cpp import *

ModuleNotFoundError: No module named 'tick.tick_cpp.tick_cpp'

[PhilipDeegan]

it looks like you're installed it inside your site-packages directory for python

I haven't verified that actually works yet given the state of the open PR.

when you built it from source, you should just be able to run it from that directory

python3 -c "import tick.tick_cpp; print(dir(tick.tick_cpp))"
['A0', 'AdaGradDouble', 'AdaGradDoubleDeserialize', 'AdaGradDoubleSerialize', ...

alternatively you can update your PYTHONPATH env var to point to your directory where you built tick

you should check if there's some libraries in the directory

~/opt/anaconda3/envs/mainenv/lib/python3.11/site-packages/tick-0.7.0.2-py3.11-macosx-11.1-arm64.egg/tick/tick_cpp

for me on windows atm I have the following, but it should be similar on linux or osx

ll tick/tick_cpp/

maybe you can copy these libraries to the site packages directory and it will work

[statisticallyinsignificant1]

No libraries in that directory. I've tried a ton of different stuff, I think I'm over my head with this one lol... will try another package.
