Download pre-trained OSSL soilVAE models from Zenodo

Source: R/download_models.R
download_ossl_models.Rd

Downloads one or both pre-trained model archives from the autoSpectra Zenodo deposit and extracts them into model_dir. After the first download, models are cached locally and loaded from disk (or from the in-memory cache via get_cached_model()) on subsequent calls to predict_soil().

Usage

download_ossl_models(
  family_id = c("OSSL_VisNIR", "OSSL_MIR"),
  model_dir = getOption("autoSpectra.model_dir", "models"),
  zenodo_record = .MODELS_ZENODO_RECORD,
  overwrite = FALSE,
  timeout_sec = 3600L
)

Arguments

family_id

Character vector of family IDs to download. One or both of "OSSL_VisNIR" and "OSSL_MIR". Default: both families.

model_dir

Local directory where models are stored. Default: getOption("autoSpectra.model_dir", "models").

zenodo_record

Zenodo record ID (string). Normally left at default.

overwrite

Logical. If TRUE, re-download even if models are already present. Default FALSE.

timeout_sec

Download timeout in seconds (default 3600 = 1 h).

Value

Invisible character vector of directories written.

Quick-start workflow


library(autoSpectra)
download_ossl_models()                  # one-time setup
predict_soil(df, "OSSL_VisNIR")         # works immediately
