Or you can install the package from source. Ensure you are in the r/validmind directory:

devtools::install()

Quick Start

You can connect to your ValidMind profile by providing the appropriate credentials:

vm_r <- vm(
  api_key="<your_api_key_here>",
  api_secret="<your_api_secret_here>",
  model="<your_model_id_here>",
  python_version="<path_to_your_python_version_here>",
  api_host="https://api.prod.validmind.ai/api/v1/tracking"
)

Fleshed out Example

Please see the notebooks/code-sharing/r folder for examples of how to use!

Troubleshooting

Initializating vm() on Mac

When calling vm() 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 the libc++ library not being found 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 a symlink 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 to the 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 of libc++ that R was trying to find.

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

Issues with Numba when 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.
