thank you for reporting this!
I run into the exact same problem when installing pyunicorn, no matter what version. The install worked until recently so I suspect the problem comes from updates in the dependencies, most probably with the C compiler or Cython itself.
In fact, as you noticed, the problem appears simply to be with the variable name I used inside the core/_ext/src_numerics.c file. It interferes with C's own macro I which is used for the imaginary unit when the complex library is included (#include <complex.h>). Although the complex library is not included in core/_ext/src_numerics.c, Cython might automatically include it. Not sure how this did not cause any problems previously, might be an update to Cython or the used C compiler. I couldn't find out about a way to direct Cython not to include the complex library. One could explicitly include the library inside the file and undefine the macro (#include <complex.h>; #undef I), but as we don't want to use complex numbers in the first place, I think simply renaming the variable is the smoother option. I will open a branch to implement that.
It would still be cool to find out what dependency actually caused this problem to pop up. This way you might still be able to use pyunicorn v0.7.0 from pip making sure to use a previous version of the respective dependency. Unfortunately couldn't figure that out yet, using older versions of Cython and setuptools didn't fix it. Any ideas are most welcome! :)

My anaconda distribution got corrupted so I had to uninstall and reinstall it to start fresh, which meant having to reinstall all my Python packages. However, I can no longer install
pyunicornvia pip or from the source code. I can't tell whether the issue is coming frompip, the version ofcondaI have now (versus what I had installed back in September) or from updates to the latest version ofpyunicorn. I've tried bothcondaandminicondafrom the Anaconda site directly and also via Homebrew (as a cask) -- all methods fail with the latest version ofpyunicorn. I was able to dopip install pyunicorn==0.6.0but then my import statementfrom pyunicorn.timeseries import RecurrencePlotfails. I've been going nuts all week about this and am very confused as to what happened. I previously installedpyunicornon this same laptop (MacBook M3) and had installed the package both via pip through Homebrew's anaconda and from the Github repo, on my old laptop (MacBook M1).Below is the error message I get for any method I've tried. It seems to be coming up when compiling _core.numerics. I'm not very familiar with C but it looks like the
numerics.cfile has a defined macro 'I' which is overwriting / interfering with the system's default 'I' macro? I even tried adding a monkey patch to a clone of the GitHub repo (also shared below) and then doingpip install .but the same error still came up. Also thought maybe the issue stemmed from my C compiler so I tried both the default version of clang as well as the clang compiler from Homebrew'sllvmpackage. No luck -- both still give me this error. There's also lots of errors or warnings related to Numpy dependencies and header files.Finally, I don't know if it's related / helpful at all but I notice on my old laptop that the distribution info was stored in an
egg.infofile instead of the now-usedpyproject.toml. I think the last time I installedpyunicornon this laptop was when it still hadegg.infometadata instead ofpyproject.toml.Here is the complete error message:
The monkey patch I tried to add:
System info: OS: Macbook M3 Max Python version: Multiple (3.10, 3.11.7, 3.12.3, 3.14.3, 3.14.4) conda version: Multiple (24.1.2, 24.4.0) miniconda version: Multiple (24.1.2, 24.4.0) pyunicorn versions: Multiple (0.6.0, 0.7.0, 0.7.0.a1 from a fork in my repositories of a previous version that has since been removed from your Github)
