        "description": "# pyzfp\nPython wrapper over the [zfp compression library](https://computation.llnl.gov/projects/floating-point-compression). This is the second version, rewritten using Cython because the earlier version using ctypes was slow. [Click here](https://github.com/navjotk/pyzfp/blob/ctypes_vs_cython/ctypes_vs_cython_compression.png) for performance comparison. Currently wraps zfp version 0.5.5. \n\n# Installation\n```\npip install pyzfp\n```\nThis should download zfp version 0.5.5, compile it and install the python (Cython) wrappers in the default install location. The use of a virtual environment is recommended.\n\nShould you face any issues, please report them using Github issues. \n\n# Usage\n\nA sample program that demonstrates the use of the library: (also contents of test.py):\n```\nfrom pyzfp import compress, decompress\n\n\na = np.linspace(0, 100, num=1000000).reshape((100, 100, 100))\n\n\n\ntolerance = 0.0000001\nparallel = True\ncompressed = compress(a, tolerance=tolerance, parallel=parallel)\n\nrecovered = decompress(compressed, a.shape, a.dtype, tolerance=tolerance)\nprint(len(a.tostring()))\nprint(len(compressed))\nprint(np.linalg.norm(recovered-a))\n```\n\n\n\n",
