Resolve the conflict between the required library versions in Python multiple projects [contrib library cannot be used for versions above tensorflow2]

1、 Problem prospect ： Existing projects paddlespeech, In this project numpy Version and new project ocr What is required is numpy Version conflict

2、 Solution ： install anaconda, Configure virtual environment

【anaconda The installation process is a little bit 】

3、anaconda Automatically create new after installation python Environmental Science （ I automatically install it here python3.9 了 ）. To install one python3.7↓

  Click on CREATE, Name yourself , Then select what you want to install python edition

conda env list： See all environments , It can detect whether the configuration is successful

4、 There's a problem here ：create It's grey and doesn't move .

solve ： open C:\Users\Administrator In the catalog .condarc file , Replace the content with

  After the save anaconda You can normally create a new virtual environment

5、 The new virtual environment has been created successfully python3.7【anaconda The interface will display the local location 】

Click the green button -》 Click on “open Terminal” Access terminal . Here you can execute pip Command to install the required libraries

6、 Input... At the terminal pip install tensorflow=1.13.1 -i http://pypi.douban.com/simple

install tensorflow1.13.1 edition .

【！！ Because the project needs tensorflow.contrib, therefore tensorflow The version of is in 1.15 following ,1.15.0 Can not be ！！ Because I am safe 1.15.0 All morning QAQ！！】

【 There are many ways on the Internet to say that there is no need to reduce the version , I tried it, but it didn't work well , Fear that the downgrade will affect other projects can anaconda Just configure a virtual environment 】

 conda list : View the installed packages in the current environment , Check whether there is a specified version of tensorflow
