Install lzip for windows12/25/2022 ![]() ![]() Lzip can also decompress data from an in-memory buffer. decompress_url_iter ( "" ): # chunk is a bytes object decompress_url ( "" ) # option 2: iterate over the decompressed file in small chunks for chunk in lzip. frombuffer ( chunk, dtype = " ![]() decompress_file_iter ( "/path/to/input.lz", word_size = 4 ): values = numpy. Read and decompress a file one chunk at a time, and ensure that each chunk contains a number of bytes that is a multiple of word_size (useful to parse numpy arrays with a known dtype): import lzip import numpy for chunk in lzip. decompress_file_iter ( "/path/to/input.lz" ): # chunk is a bytes object Read and decompress a file one chunk at a time (useful for large files): import lzip for chunk in lzip. Read and decompress a file to an in-memory buffer: import lzip buffer = lzip. Lzip can use different compression levels. ![]() compress_to_file ( "/path/to/output.lz", values. close ()Ĭompress a Numpy array and write the result to a file: import lzip import numpy values = numpy.

FileEncoder ( "/path/to/output.lz" ) as encoder : encoder. compress_to_file ( "/path/to/output.lz", b "data to compress" )Ĭompress multiple chunks and write the result to a single file (useful to avoid large in-memory buffers): import lzip with lzip. pip3 install lzipĬompress an in-memory buffer and write it to a file: import lzip lzip. URLs can be used as well to download, decompress and process the chunks of a remote Lzip archive in one go. Decoding and encoding can be performed in chunks, enabling the decompression, processing and compression of files that do not fit in RAM. This package is compatible with arbitrary byte sequences but provides features to facilitate interoperability with Numpy's frombuffer and tobytes functions. See also the CMake 3.23 Release Notes.Lzip is a Python wrapper for lzlib ( ) to encode and decode Lzip archives ( ). To build the source distributions, unpack them with zip or tar and follow the instructions in README.rst at the top of the source tree. This prefix can be removed as long as the share, bin, man and doc directories are moved relative to each other. For example, the linux-x86_64 tar file is all under the directory cmakeâlinux-x86_64. They are prefixed by the version of CMake. The tar file distributions can be untared in any directory. The files are compressed tar files of the install tree. The files are gziped tar files of the install tree. sh file, run it with /bin/sh and follow the directions. sh files are self extracting gziped tar files. The release was packaged with CPack which is included as part of the release. See also the CMake 3.24 Release Notes.Īlso see instructions on Download Verification. ![]()
