[ENH] loaders for MONSTER datasets 6 months ago

AI Summary: This GitHub issue proposes adding loaders for various "MONSTER datasets" to the `aeon` library's datasets module. The suggested implementation uses `huggingface_hub` to download the data, which would introduce it as an optional dependency. The author is also seeking alternative methods to load these datasets to potentially avoid this new dependency.

[BUG] np.int_ causes 32-bit Overflow on Windows (NumPy < 2.0) 7 months ago

AI Summary: This GitHub issue reports a critical platform-dependent bug where `np.int_` maps to a 32-bit integer on Windows (even 64-bit systems) but a 64-bit integer on Linux/macOS. This discrepancy causes `OverflowError` or silent data corruption in applications like `aeon` when handling indices or strides larger than 2.14 billion on Windows, effectively breaking large-scale time series processing. The problem arises from the use of `np.int_` in core utilities, and the suggested resolution is to replace it with a fixed-width integer type like `np.int64`.
