lagllama_freq

Frequency strings for Lag-Llama / GluonTS (no torch imports — safe for lightweight tests).

normalize_freq_for_lagllama(freq)

Map pipeline / pandas-2.2 freq aliases to strings GluonTS + pandas accept.

Multivariate tasks often carry ME / QE / YE from metadata; GluonTS 0.14 raises KeyError / invalid frequency for those aliases. Normalize to legacy M / Q / Y / AS first, then hour/minute/second spellings for pandas.

Parameter	Type	Default	Description
freq	str	-	(undocumented)

Returns: str (The normalized frequency string.)
