Проблемы с pydot и graphviz

Most of the people gave great insights, here's a procedure which I find useful for myself -

assumed conf. -> Anaconda 4.4.0 or higher, Win 8+, and using anaconda prompt

• Few required installations (no order necessary)
  1. pip install pydot-ng
  2. conda install graphviz
  3. pip install graphviz
• PATH setting -> Under user environment variables add C:/Anaconda/Library/bin/graphviz in PATH (not Path)
• Go to C:/Anaconda/Lib/site-packages/keras/utils/
  Now open vis_utils.py in an editor and change line 11 from import pydot to import pydot_ng as pydot
• All set, now go to Jupyter notebook and type following commands -
  import graphviz
import pydot_ng as pydot
pydot.find_graphviz()
  If everything went well then you will find something similar to as shown below -
  {'circo': 'C:\\Anaconda\\Library\\bin\\graphviz\\circo.exe',
'dot': 'C:\\Anaconda\\Library\\bin\\graphviz\\dot.exe',
'fdp': 'C:\\Anaconda\\Library\\bin\\graphviz\\fdp.exe',
'neato': 'C:\\Anaconda\\Library\\bin\\graphviz\\neato.exe',
'sfdp': 'C:\\Anaconda\\Library\\bin\\graphviz\\sfdp.exe',
'twopi': 'C:\\Anaconda\\Library\\bin\\graphviz\\twopi.exe'}
