Installation fail

[p-matt]

Starting from scratch with an empty venv, there is an empty .toml

requires-python = "=3.13"
dependencies = [
]

poetry add tabpfn-time-series will throw an error :

...
  - not supporting PEP 517 builds
  - not specifying PEP 517 build requirements correctly
  - the build requirements are incompatible with your operating system or Python version
  - the build requirements are missing system dependencies (eg: compilers, libraries, headers).

You can verify this by running pip wheel --no-cache-dir --use-pep517 "pandas (==2.1.4)".

Windows, python 3.13

@p-matt

Sorry about the issue!

I personally am not so familiar with poetry. Could you maybe try again with python 3.10, 3.11, or 3.12? These are the versions that are in the CI tests.

[p-matt]

I'll not be able to try on another python version, sorry for that ...

Could you try to find out if it's a dependency or TabPFN itself? I suspect the first, since we specify python > 3.10

I am also having issues installing the dependencies.

Steps I took:

1. clone the repo
2. cd into tabpfn-time-series then run uv sync

Error I am getting seems to be when installing llvmlite which is a dependency for tabpfn-time-series

Full trace back:

      hint: This usually indicates a problem with the package or the build environment.
  help: `llvmlite` (v0.45.1) was included because `tabpfn-time-series` depends on `tabpfn` (v6.0.4) which depends on `kditransform` (v1.2.0) which depends on `numba`
        (v0.62.1) which depends on `llvmlite`

Environment details:
OS: Linux, Omarchy 3.0
Python version: 3.14

Could this be OS specific issue? Any pointers will be much appreciated.

I think you might have to install cmake on your system?
