v0.0.35

Features

• PatchTST-FM family checkpoints: Document and compare IBM Research and Granite PatchTST-FM releases via the existing PatchTSTFM class (foundationforecast>=0.1.8, granite-tsfm>=0.3.8). Pass repo_id to select the checkpoint:

  • ibm-research/patchtst-fm-r1 (default) — CC-BY-NC-SA-4.0 (non-commercial research weights)
  • ibm-granite/granite-timeseries-patchtst-fm-r1 — Apache-2.0
  • ibm-granite/granite-timeseries-patchtst-fm-r2 — Apache-2.0 / OpenMDW 1.0 (dual-licensed; commercial-friendly)

  import pandas as pd
  from timecopilot.models.foundation.patchtst_fm import PatchTSTFM
  
  df = pd.read_csv(
      "https://timecopilot.s3.amazonaws.com/public/data/air_passengers.csv",
      parse_dates=["ds"],
  )
  
  model = PatchTSTFM(
      repo_id="ibm-granite/granite-timeseries-patchtst-fm-r2",
      alias="Granite-PatchTST-FM-r2",
      context_length=2048,
  )
  fcst_df = model.forecast(df, h=12, freq="MS", level=[80, 90])

  License note: Only the IBM Research checkpoint (ibm-research/patchtst-fm-r1) is non-commercial (CC-BY-NC-SA-4.0). Granite PatchTST-FM r1 and r2 use permissive open licenses suitable for commercial use (see model cards above).

• PatchTST-FM family notebook: Added patchtst-fm-family example notebook comparing IBM Research patchtst-fm-r1 with Granite patchtst-fm-r1 and patchtst-fm-r2, including prediction intervals and evaluation metrics.

Dependencies

• Bumped foundationforecast from >=0.1.7 to >=0.1.8 (Granite PatchTST-FM r2 via granite-tsfm>=0.3.8).
