Setting up Conda Environment for Swagger and Scrapy based project

We have a file that reads "my_yml.yml":

name: swagger2
channels:
  - conda-forge
  - defaults
dependencies:
  - beautifulsoup4
  - connexion
  - flask
  - flask_cors
  - scrapy 

It will do these three things:

1. It will create an environment "swagger2".

2. For downloading packages, it will use the channels: "conda-forge" and "defaults"

3. The packages it will install are mentioned as "dependencies".

Checking our current environments:
(base) C:\Users\Ashish Jain>conda env list 
# conda environments:
base      *  E:\programfiles\Anaconda3
env_py_36    E:\programfiles\Anaconda3\envs\env_py_36
tf           E:\programfiles\Anaconda3\envs\tf 

(base) C:\experiment_with_conda>conda env create -f my_yml.yml
