As currently implemented,
get_loaded_model
inspects the$LOAD_PATH
global for path values when trying to find the path for a model file. This would be fine, except that variable is affected by userspace, which means that it will sometimes contain non-string values, often Pathnames. To avoid responding with the errorUnable to annotate #{model_path}: no implicit conversion of Pathname into String
in this situation, we simply add an explicitto_s
call before performing string-specific operations.Thanks to @a0s for doing the investigation here, and identifying exactly what needed to be changed in order to resolve this issue!
Fixes #758
