Hello, this is a great library for backtesting. But there's a little bit version conflict when I'm using:

I use poetry for version control, I just using poetry add lucit-backtesting and poetry add pandas.

Here is part of my pyproject.toml content:

[tool.poetry.dependencies]
python = "^3.10"
lucit-backtesting = "^1.0.0"
pandas = "^2.2.2"

as version resolving results, numpy version is 2.0.1，and error happens.
I can change the wrong line in site-packagaes, but in test environment, it's not a good way.
Could we update bokeh version? or there's any environment constraint files files provide?

I also encountered this error. I did the following:
pip uninstall numpy
pip install numpy==1.23.5

[xaritoku]

I also encountered this error. I did the following: pip uninstall numpy pip install numpy==1.23.5

Thank you!

But I wonder would it be possible to update the bokeh constraints in setup.py? This change could make the library easier to install.

I tested the following poetry dependencies, and they worked fine with the library's code:

[tool.poetry.dependencies]
python = "^3.10"
numpy = "<2.0.0"
pandas = "^2.2.2"
bokeh = "^3.5.1"

Could we consider loosening the bokeh version constraint to support this configuration? Changing this line:
