🚀 启动

• 安装Python3.7.7
• 下载PyCharm
• 配置pip源

路径:
C:\Users\Administrator\pip\pip.ini
内容:
[global]
index-url = https://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host=mirrors.aliyun.com

🌰 配置环境

• 下载Python3
• 配置环境变量

  PYTHON_HOME=C:\Python37
  PATH=%PYTHON_HOME%;%PYTHON_HOME%\Scripts;

• 安装django

  python -m pip install  django  
  python -m django --version

• 创建项目

  django-admin.py startproject foot_tensorflow

• PyCharm打开foot_tensorflow

  PyCharm配置一下venv
  venv没有继承Python全局环境下的包的话,再安装一下django  
  pip install  django

🌰 使用django生成model

• 在settings.py文件中配置数据连接信息

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'foot',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': '127.0.0.1',
        'PORT': 3306
    }
}

• 生成模型文件 python manage.py inspectdb

    出现错误 ModuleNotFoundError: No module named 'MySQLdb'
    python2和python3在数据库模块支持这里存在区别，
    python2是mysqldb，而到了python3就变成mysqlclient，
    pip install mysqlclient

• 将模型文件导入到app当中

    创建app python manage.py startapp foot
    将模型导入创建的app中 python manage.py inspectdb > foot/models.py

🌰 安装TensorFlow

• pip install tensorflow==2.0.0

    Windows下只适合安装Tensorflow2.0.0 
    默认的版本2.1会出现加载模块错误

🌰 同步依赖配置

• pip freeze > requirements.txt
• pip install -r requirements.txt

🌰 错误记录

• 🎯 错误1

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, 
but settings are not configured. 
You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() 
before accessing settings.

• ☕ 处理1

方式1:
import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'foot_tensorflow.settings')

import django

django.setup()
方式2:
设置运行的环境变量
DJANGO_SETTINGS_MODULE=foot_tensorflow.settings

• 🎯 错误2

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

• ☕ 处理2

注意代码的顺序
import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'foot_tensorflow.settings')

import django

django.setup()

• 🎯 错误3

RuntimeError: Model class ft.models.TAnalyResult doesn't declare 
an explicit app_label and isn't in an application in INSTALLED_APPS.

• ☕ 处理3

settings.py文件下的INSTALLED_APPS添加app包名称
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'ft',
    'tf',
]
