?? 啟動

• 安裝Python3.7.7
• 下載PyCharm
• 配置pip源

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

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

?? 配置環境

• 下載Python3
• 配置環境變量

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

• 安裝django

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

• 創建項目

  django-admin.py startproject foot_tensorflow

• PyCharm打開foot_tensorflow

  PyCharm配置一下venv
  venv沒有繼承Python全局環境下的包的話,再安裝一下django  
  pip install  django

?? 使用django生成model

• 在settings.py文件中配置數據連接信息

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

    出現錯誤 ModuleNotFoundError: No module named 'MySQLdb'
    python2和python3在數據庫模塊支持這里存在區別，
    python2是mysqldb，而到了python3就變成mysqlclient，
    pip install mysqlclient

• 將模型文件導入到app當中

    創建app python manage.py startapp foot
    將模型導入創建的app中 python manage.py inspectdb > foot/models.py

?? 安裝TensorFlow

• pip install tensorflow==2.0.0

    Windows下只適合安裝Tensorflow2.0.0 
    默認的版本2.1會出現加載模塊錯誤

?? 同步依賴配置

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

?? 錯誤記錄

• ?? 錯誤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.

• ? 處理1

方式1:
import os

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

import django

django.setup()
方式2:
設置運行的環境變量
DJANGO_SETTINGS_MODULE=foot_tensorflow.settings

• ?? 錯誤2

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

• ? 處理2

注意代碼的順序
import os

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

import django

django.setup()

• ?? 錯誤3

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

• ? 處理3

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