Decompressing 7z archive using py7zlib gives *** ValueError: data error during decompression

由 佐手、 提交于 2019-12-11 02:39:44
问题 My code is as follows (from here: Example of how to use PyLZMA) import py7zlib ... #filename.__class__ is <class 'django.core.files.uploadedfile.InMemoryUploadedFile'> archive = py7zlib.Archive7z(filename) data = archive.getmember(archive.getnames()[0]).read() The error that I get is: *** ValueError: data error during decompression The archive I am testing with is a driver compressed in 7z downloaded from the manufacturer's website. I have also used 7zip to create a 7z archive to test with,

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I want to decompress a 7zip/lzma archive with multiple files & directories in Java. I tried to use the official 7zip SDK, but I failed, as my programming skills are not that advanced for this subject. However I fonud some libraries which make the support in Java easier, speaking of LzmaOutputStream

Ho to setup and use the LZMA compression algorithm SDK

问题 Making some research on the net, I found that one of the most recent, optimized and high-performance algorithms for data compression, especially in term of compression ratio and decompression time is the LZMA Algorithm. It's supported in many popular software like WinRAR, WinZip, and 7-Zip (By default). I have found the LZMA SDK here http://www.7-zip.org/sdk.html But i haven't found a way to install it in windows or to use the source code provided (examples). For example : In DOC ==> 7cC.txt

问题 I am working on a compession/decompression project using the LZMA SDK. The main program contains some arguments that I must use to run the application To run it from the command line, I use : ./LzmaUtil.exe e input.elf output.elf I'm using VS 2013 , so i have added e in.elf out.elf to the commands arguments, I rebuild the project (the executable file in generated) but nothing seems to happen when I press RUN. Note that I have the input.elf in the debug folder were the .exe is present there,

Python LZMA : Compressed data ended before the end-of-stream marker was reached

问题 I am using the built in lzma python to decode compressed chunk of data. Depending on the chunk of data, I get the following exception : Compressed data ended before the end-of-stream marker was reached The data is NOT corrupted. It can be decompressed correctly with other tools, so it must be a bug in the library. There are other people experiencing the same issue: http://bugs.python.org/issue21872 https://github.com/peterjc/backports.lzma/issues/6 Downloading large file in python error:

Python decompression relative performance?

由 我的未来我决定 提交于 2019-12-06 06:18:44
问题 TLDR; Of the various compression algorithms available in python gzip , bz2 , lzma , etc, which has the best decompression performance? Full discussion: Python 3 has various modules for compressing/decompressing data including gzip , bz2 and lzma . gzip and bz2 additionally have different compression levels you can set. If my goal is to balance file size (/compression ratio) and decompression speed (compression speed is not a concern), which is going to be the best choice? Decompression speed
