python2.6中子样本0.0.6的错误

Question

I am trying to run the subsample0.0.6 package in python2.6.6 (to be able to run something like "> subsample -n 1000 big_data.csv" in python)

after installing subsample it seems to work at first after I check with "import subsample", but then when I move to a different directory and attempt to run the command, I get an error. Can anyone tell what is going on, or what I should do from here?

Answer 1

该程序包有自己的名为subsample的可执行文件，因此您需要按以下方式调用命令：

$ subsample -n 1000 deseq.csv > s_des.csv
