I want to be able to create graphical decision trees in Python, and I am currently trying to install both pydot
and graphviz
.
I am using Anaconda as my environment (along with Spyder), and have tried to run the following lines of code
conda install -c https://conda.binstar.org/t/TOKEN/j14r pydot
with the result
Error: unknown host: http://repo.continuum.io/pkgs/pro/win-32/
Error: unknown host: http://repo.continuum.io/pkgs/free/win-32/
Error: unknown host: https://conda.binstar.org/t/TOKEN/j14r/win-32/
Error: No packages found matching: pydot
I have also tried using pip install pydot
and pip install graphviz
with similar results:
Downloading/unpacking pydot
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pydot
Cleaning up...
No distributions at all found for pydot
Storing complete log in [...]
I am getting pretty bored at trying to figure out how to go about this, so I was hoping anyone out there could give me some tips perhaps.
Thanks
I had the same issue and solved it by (order is important):
graphviz
, simply via sudo apt-get install graphviz
graphviz
for Python via conda sudo ~/anaconda2/bin/conda install graphviz
pydot
using conda sudo ~/anaconda2/bin/conda install pydot
This answer is overdue but this post helped me (together with this one that mentions the installation order), so hopefully this answer will help someone else. I'm using Ubuntu 14.04 and Python 2.7.
P.S. apparently, there could be some issues with step 1 of the above algorithm, this post mentions how to fix them.
