Please see thenotebooks/code-sharing/r folder forexamples of how to use!

Troubleshooting

Initializating vm() on Mac

When callingvm() you might see the following error:

OSError: dlopen(/Users/user/validmind-sdk/.venv/lib/python3.11/site-packages/llvmlite/binding/libllvmlite.dylib, 0x0006): Library not loaded: @rpath/libc++.1.dylib  Referenced from: <F814708F-6874-3A38-AD06-6C06514419D4> /Users/user/validmind-sdk/.venv/lib/python3.11/site-packages/llvmlite/binding/libllvmlite.dylib  Reason: tried: '/Library/Frameworks/R.framework/Resources/lib/libc++.1.dylib' (no such file), '/Library/Java/JavaVirtualMachines/jdk-11.0.18+10/Contents/Home/lib/server/libc++.1.dylib' (no such file), '/var/folders/c4/typylth55knbkn7qjm8zd0jr0000gn/T/rstudio-fallback-library-path-492576811/libc++.1.dylib' (no such file)

This is typically due to thelibc++ library not beingfound but it’s possible that is already installed and R cannot find it.You can solve this by finding the path to the library and creating asymlink to it.

# Find the path to libc++.1.dylib. This can return multiple results.sudo find / -name "libc++.1.dylib" 2>/dev/null

If you are using Homebrew, the command above will return a path like/opt/homebrew/Cellar/llvm/.... You can create a symlink tothe library by running the following command:

sudo ln -s <path_to_libc++.1.dylib> /Library/Frameworks/R.framework/Resources/lib/libc++.1.dylib

Note that the target argument in the path oflibc++ thatR was trying to find.

After creating the symlink, you can try callingvm()again.

Issues with Numbawhen initializing vm() on Mac

You might also see the following error when initializing vm():

Error in py_module_import(module, convert = convert) :  ImportError: cannot import name 'NumbaTypeError' from partially initialized module 'numba.core.errors' (most likely due to a circular import) (/Users/user/validmind-sdk/.venv/lib/python3.11/site-packages/numba/core/errors.py)

To fix this, you can reinstall Numba:

pip install -U numba

And restart the R session.
