我们在对GROMACS在鲲鹏920上的运行性能分析与调优过程的实践中,受限于GROMACS复杂的输出日志,无法快速提取日志中相关的性能数据,基于Python开发了一个日志读取脚本,可以将所关心的性能数据统一抓取到csv中,便于数据的对比分析。具体如下: 环境: Linux、Python3、openyxl 脚本内容: #!/usr/bin/env python import os...
使 dlt可以在脚本中处理的几乎所有格式的数据，将其加载到数据集中。该库将自动创建/更新表、推断数据类型并处理嵌套数据，包括：JSON、CSV/XLS/Pandas、Web API、数据库等，比如加载应json数据：import dlt from dlt.common import json with open("./assets/chongchong.json", 'rb') as file:data = json....
首先加载pandas,以使用DataFrame及相关方法来读写数据。注意,关键词as赋给pandas一个别名pd。这样在后面的代码中,使用DataFrame或read_csv(...)方法时,我们就不用写出包的全名了。我们将(用于读和写的)文件名分别存于变量r_filenameCSV(TSV)和w_filenameCSV(TSV)。
