pysiglib.clear_cache

Added in version v1.0.0.

clear_cache(*, use_disk=False, device='both')

Clears the cache generated by pysiglib.prepare_log_sig.

Parameters:

• use_disk (bool) – If False, will clear the cache from memory only. If True, will also clear the shared disk cache directory. See additionally the documentation for pysiglib.set_cache_dir.

• device (str) – Which device caches to clear. Must be one of "cpu", "cuda", or "both" (default).

Example:

import torch
import pysiglib

pysiglib.prepare_log_sig(dimension=5, degree=4, method=2, use_disk=True)

path = torch.rand((10, 100, 5))
log_sig = pysiglib.log_sig(path, 4, n_jobs = -1)
print(log_sig)

pysiglib.clear_cache() # Clear cache from memory but keep on disk
