Package compatibility (original) (raw)
This document lists Python packages that are known to be supported or unsupported by IronPython. For a generic discussion about compatibility with Python packages see Running Python packages from PyPI.
Note
To install a Python module from PyPI, first perform a one-time preparation of a fresh IronPython installation or environment:
ipy -m ensurepip
ipy -m pip install --upgrade pip
ipy -m pip install --upgrade setuptools
Warning
IronPython does not currently support packages which are CPython extension modules (i.e depend on CPython's .dll/.so/.dylib).
⚠️ Known unsupported packages
| Unsupported package | Reason |
|---|---|
| numpy | CPython extension module |
| pandas | requires numpy |
| scipy | requires numpy |
| opencv-python | requires numpy |
| pytorch | requires numpy |
| scikit-learn | requires numpy |
| onnx | requires numpy |
| dedupe | requires numpy |
| imutils | requires numpy |
🟢 Known supported packages
pytest (4.6.11)
To install:
ipy -m pip install pytest==4.6.11 typing==3.10.0.0
The package fails with (probably the same issue as https://github.com/IronLanguages/ironpython3/issues/1212):
SystemError: Cannot access a closed file.
Edit _pytest/capture.py and replace:
with f: tmpfile = safe_text_dupfile(f, mode="wb+")
with:
tmpfile = EncodedFile(f, getattr(f, "encoding", "utf-8"))
requests (2.21.0)
To install:
ipy -m pip install requests==2.21.0
sympy (1.4)
To install:
ipy -m pip install sympy==1.4
The above will also automatically install mpmath 1.2.1 if not yet installed.
sympy comes with an interactive console, which can be started with:
