我正在学习关于在 ubuntu 20.04 上设置火炬的教程，其中一行需要设置pyenv，就像 python 的 virtualenv 这样我可以运行多个版本的 python。有点不必要，但这是一个学习过程，也是学习另一天我可能会使用的另一种新工具的好机会。
所以这个命令在成功设置 pyenv 后失败了
sam@sam:~/torch$ pyenv virtualenv 3.8.2 torch
pyenv: no such command `virtualenv'
所以为了涵盖我的基础知识，我已经安装了 virtualenv，如下所示
sam@sam:~/torch$ virtualenv

import pandas as pd
import numpy as np
df = pd.read_csv(filename_read)
ids = df['id']
oosDF = pd.DataFrame()
oosDF['id'] = ids
oosDF['pred'] = pred
oosDF['y'] = df['target']
#oosDF['diff'] = oosdF['pred'] - oosDF['y']
#oosDF['diff'] = oosDF.abs()

自从我将django设置为在本地工作以来已经有一段时间了。我正在使用version 1.11。获取它来提供静态文件。调用了我的项目chatsys，并在此文件夹中创建了静态文件夹和CSS chatsys\static\css\style.css。
这是设置文件中的当前设置。
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
并在网址中
#for serving static files
from django.conf import settings
from django.conf.urls.static import static
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
最后在html中
{% load static %}

<link rel="stylesheet" type="text/css" href="/static/css/style.css">
但是在运行服务器控制台中，我得到404 /static/css/style.css
