#

# To activate this environment, use

# $ conda activate env_py_36

#

# To deactivate an active environment, use

# $ conda deactivate

#

# To list all the environments (active environment is marked with an *):

# (base) C:\Users\ashish>conda info -e

# conda environments:

# base * C:\Users\ashish\AppData\Local\Continuum\anaconda3

# env_py_36 C:\Users\ashish\AppData\Local\Continuum\anaconda3\envs\env_py_36

=================================================

Note: Rasa-core requires a package "Twisted" and Twisted requires "Microsoft Visual C++ 14.0", otherwise it will fail to install. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/"

To install Rasa and Spacy, fire these two "pip" commands:

pip install rasa-core

pip install spacy

=================================================

Note: If you are getting network errors while downloading a package using "pip" command, then you can directly download the required package matching with your Python version from this URL: https://files.pythonhosted.org/

(env_py_36) C:\Users\ashish\Desktop>pip install klein

Tip: To avoid typing "pip install" again and again in the prompt while installing a packages using WHL files, you can create a command alias in Windows Command Prompt as follows:

(env_py_36) C:\Users\ashish\Desktop>doskey pi=pip install $*

(env_py_36) C:\Users\ashish\Desktop>pi incremental-17.5.0-py2.py3-none-any.whl
