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

以下是我尝试使用“>>>”表示每个问题的方法。

有没有更好的方法我不知道？

如何在 Tkinter 中运行 python 文件

from subprocess import Popen
p = Popen("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()

>>>OSError: [WinError 193] %1 is not a valid Win32 application

从另一个 Python 脚本运行 Python 脚本，传入参数

import os
os.system("C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py --temperature 0.8 --top_k 40 --model_name run1 --nsamples  1 --length 100")

>>>(Script does not complete and output is not gathered)

将 os.system 的输出分配给一个变量并阻止它显示在屏幕上

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()

>>>(doesnt run it)

如何在给定完整路径的情况下导入模块？

import importlib.util
spec = importlib.util.spec_from_file_location("generate_unconditional_samples", "C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py")
foo = importlib.util.module_from_spec(spec)
spec.loader.exec_module(foo)
foo.MyClass()

>>>ModuleNotFoundError: No module named 'fire'(fire is the first import call in the module also no augments)

Python：在执行 cmd 命令时读取输出

command='cmd /C C:\GPT2\gpt-2-finetuning\src\generate_unconditional_samples.py --temperature 0.8 --top_k 40 --model_name run1 --nsamples  1 --length 100'
proc=Popen(command,creationflags=CREATE_NEW_CONSOLE,stdout=PIPE)
output=proc.communicate()[0]
print (output)

>>>b''(thats the full output)

预期执行

也许尝试调用 python 可执行文件（确保“python.exe”在路径中或指定完整路径）：

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()

您的参数中还有一些拼写错误（run1 后没有空格，--nsamples 后有两个空格）。您始终可以将参数列表传递给 Popen 以不必管理它：

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()
