How to use conda to install pydot?

Question

Trying to generate some PDF of decision tree by following some sklearn docs but cannot get Pydot on my machine. Is there a way to use the conda installer to install the pydot package? Based on the command line errors that I see, this may be a problem with the 64-bit version. I use binstar search to find the package channel:

C:\binstar search -t conda 

This gives recommendations for viewing packages in detail using

 binstar show j14r/pydot 

What then tells me

 conda install --channel https://conda.binstar.org/j14r pydot 

But when I run the conda install command, I get the following error (same error for all pydot packages listed):

 Fetching package metadata: ... Error: No Packages found in current win-64 channels matching: pydot You can search for this package with binstar search t conda pydot 

which brings me back to the beginning of it all. Any ideas? Thanks to everyone.

This might help someone who is looking for Anaconda on Windows 10 64 bit, Environment: Windows 10 64 bit, Python 3.5.2, Anaconda 4.2.0 (64-bit)

• Download "graphviz-2.38.msi" from http://www.graphviz.org/Download_windows.php
• Execute the file "graphviz-2.38.msi"
• Add the graphviz bin folder to the PATH system environment variable (Example: "C: \ Graphviz2.38 \ bin")
• Go to Anaconda Prompt using the Start menu (be sure to right-click and select "Run as administrator"). We can get permissions if the "Invitation" does not open as "Administrator").
• Run the command: conda install graphviz
• Run the command: pip install git + https://github.com/nlhepler/pydot.git
• Run the cond list command and make sure the pydot and graphviz modules are listed. Thanks

I had the same question for my installation of Anaconda3 x64 on Windows 8.1.

Here is what I did:

1) Installed Github for Windows https://windows.github.com/

2) Opened a Git shell (this is a PowerShell session that allows Git commands)

3) Install pydot from https://github.com/nlhepler/pydot with this command:

 ./pip install git+https://github.com/nlhepler/pydot.git 

4) You can check if pydot has been installed by releasing

 conda list 

Answer 3

Try the following:

 conda install -c https://conda.binstar.org/sstromberg pydot 

Answer 4

New pydot link for 64-bit installer https://anaconda.org/rmg/pydot or just

conda install -c rmg pydot

Answer 5

Most people gave a great overview, here is a procedure that I find useful to myself -

Suppose → Anaconda 4.4.0 or later, Win 8+ and using the anaconda command

• Few required installations (no order required)
  1. pip install pydot-ng
  2. conda install graphviz
  3. pip install graphviz
• PATH -> In user environment variables add C: /Anaconda/Library/bin/graphviz to PATH (not path)
• Go to C: /Anaconda/Lib/site-packages/keras/utils/
  Now open vis_utils.py in the editor and change line 11 from import pydot to import pydot_ng as pydot
• Everything is configured, now go to the Jupyter laptop and enter the following commands -
  import graphviz
import pydot_ng as pydot
pydot.find_graphviz()
  If all goes well, you will find something similar, 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'}

Answer 6

It looks like the j14r pydot package is built for 32-bit Windows, but I assume you are using a 64-bit cond. See https://conda.binstar.org/j14r .

Answer 7

Try this (from Anaconda Prompt):

 conda install pydot-ng 

Then in your code:

 try: import pydot_ng as pydot except ImportError: import pydot # if someone running with old installation
