在python文件中运行一个python命令，并读取输出

我是python新手，正在尝试将此命令的输出转换为字符串

C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py --temperature 0.8 --top_k 40 --model_name run1-- nsamples  1 --length 100

下面是我用“>>>>”尝试过的东西，表示每个问题

有没有更好的方法我不知道

Python3.7 spyder

预期执行

也许可以尝试调用python可执行文件（确保“python.exe”位于路径中或指定完整路径）：

参数中也有一些输入错误（run1后面没有空格，--nsamples后面有两个空格）。您可以始终将参数列表传递给Popen，以便不必管理此参数：

from subprocess import Popen
p = Popen(["python", "C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py", "--temperature",  "0.8", "--top_k", "40", "--model_name", "run1", "--nsamples", "1", "--length", "100"])
stdout, stderr = p.communicate()

---

谢谢你的回复！不幸的是，仍然没有存储到stderr或stdout的值，并且代码似乎没有运行，因为它通常是一个非常CPU密集的进程，并且没有检测到CPU使用率的增加。

text = os.popen('cat C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py --temperature 0.8 --top_k 40 --model_name run1 --nsamples  1 --length 100').read()
