Compress and decompress a numpy array of float64.

from pcodec import compress, decompress import numpy as np data = np.array([1.0, 2.5, 3.2, 4.8, 5.1], dtype=np.float64) compressed = compress(data) decompressed = decompress(compressed, dtype=np.float64) print(decompressed)

pcodec --version

Debug

Known issues

breakingIn v1.0.0, function arguments were renamed: 'nums' became 'src', and 'none' delta encoding became 'no_op'.

fix

Update calls: compress(src=...) and use delta_encoding='no_op' instead of 'none'.

affects: >=1.0.0,<1.0.0

breakingIn v1.0.0, simple_compress_into now accepts any Write impl (Rust change); Python API may have changed signature.

fix

Check pcodec documentation for current function signatures.

affects: <1.0.0

gotchaCompression and decompression require numpy arrays; other iterables may not work.

fix

Convert your data to a numpy array with the correct dtype before calling compress.

affects: all
