GraalVM provides an early-stage experimental implementation of Python. A primary goal is to support SciPy and its constituent libraries. This Python implementation currently aims to be compatible with Python 3.7, but it is a long way from there, and it is very likely that any Python program that requires any imports at all will hit something unsupported. At this point, the Python implementation is made available for experimentation and curious end-users.
To try it, you can use the bundled releases from www.graalvm.org. For more information and some examples of what you can do with it, check out the reference.
At the moment not enough of the standard library is implemented to run the standard package installers for many packages. As a convenience, we provide a simple module to install packages that we know to be working (including potential patches required for those packages). Try the following to find out more:
graalpython -m ginstall --help
As a slightly more exciting example, try:
graalpython -m ginstall install numpy
If all goes well (you'll need to have clang, llvm-link, llvm-extract,
llvm-nm, and opt in your PATH in addition to the normal NumPy build
dependencies), you should be able to import numpy afterwards.
Support for more extension modules is high priority for us. We are actively building out our support for the Python C API to make extensions such as NumPy, SciPy, Scikit-learn, Tensorflow and the like work. This work means that some other extensions might also already work, but we're not actively testing other extensions right now and cannot promise anything. Note that to try extensions on this implementation, you have to download, build, and install them manually for now. To do so, we recommend LLVM 6. Other versions might also work, but this version is what we're testing with in our CI.
