I solved with this 2 steps:
- install Graphviz after download installer (https://www.graphviz.org/)
- insert in code this two lines:
import os
os.environ["PATH"] += os.pathsep + 'C:/Program Files (x86)/Graphviz2.38/bin/'
from deepreinforcementlearning.
brew install graphviz
or equivalent should fix this
from deepreinforcementlearning.
@jbarrigapartarrieu make sure you have Graphviz installed separately on your system, not just in your project directory. You can find source and executable package installers here: https://www.graphviz.org/download/
in Ubuntu, I use 'apt-get install graphviz', then , it sovled.
from deepreinforcementlearning.
@Kiran-kkt You need to install Graphviz with conda, and not from the binaries.
See here for syntax: https://anaconda.org/anaconda/graphviz
It's probably better to uninstall Graphviz first, but actually I'm not sure if there would be any clash.
Reason: Pydot checks whether you have graphviz installed by calling the dot
executable. On Windows it appends an extension "exe" unless you have Anaconda, in which case it appends "bat". You can check that your Graphviz installation from binaries has only "dot.exe". So since pydot tries to execute "dot.bat" you;'re getting the error.
You can see it in Pydot's sources here: https://github.com/pydot/pydot/blob/master/pydot.py#L103-L108

It worked with the following command on windows 10:
conda install graphviz
from deepreinforcementlearning.
If you have setup the PATH variable in Windows and still the same error shows up in any IDE like PyCharm, then restart your IDE. It fixes the error as the PATH variable does not get updated dynamically.

@MirkosMartins The issue still persists for me even after doing the same as you did.

I solved with this 2 steps on Linux
- conda install -c conda-forge graphviz
- restart jupyter notebook
then ,it solved!

I used https://stackoverflow.com/questions/40632486/dot-exe-not-found-in-path-pydot-on-python-windows-7 to get past a similar issue
from deepreinforcementlearning.
On Windows 10:
- Run PowerShell as Adnin
dot -c

I had the same issue and the install of graphviz via Anaconda solved it for me on Windows 8.1.
I used this one:
conda install -c anaconda python-graphviz
I found it at the link below.

Line #24 #25 suggests me that its checking for graphviz installation. I've also looked up in stackoverflow and I see the same answer
I also tried this by installing python package anaconda python-graphviz but of no use.
I don't understand why this problem still exsists it's kind of wierd.
from deepreinforcementlearning.
Sorry to hear that @Kiran-kkt, this solution worked on my machine :(.
Anyway, the error you're getting says that the subprocess ended with exit code = 1.
Are you also getting an error message (just before the AssertionError) - something like
message = '"{prog}" with args {arguments} returned code: {code}\n\n'
'stdout, stderr:\n {out}\n{err}\n'
Maybe that gives more details as to what is going on?
This message is formed and displayed in the latest version of pydot, but from the line numbers in your stack trace I can see that you have some older version. Could you check what version that is? (e.g. by running pip freeze
from the command line inside the virtual environment)
from deepreinforcementlearning.
@onomatopeia Thanks. Installing with conda worked for me.
from deepreinforcementlearning.
@onomatopeia Here is the message
"dot" with args ['-Tps', 'C:\\Users\\TUNUGU~1\\AppData\\Local\\Temp\\tmp4dwfnf5z'] returned code: 1
stdout, stderr:
b''
b''
pydot version is 1.4.1 and graphviz version is 2.38
from deepreinforcementlearning.
Ah, that is so unhelpful!
Ok, some last checks before I give up.
In the command line activate your virtual env, type where dot
. This is just a sanity check, the path should be something like <path_to_anaconda>\envs\<your_virtual_env>\Library\bin\dot.bat
.
Then check that this file actually exists: C:\\Users\\TUNUGU~1\\AppData\\Local\\Temp\\tmp4dwfnf5z
(I copied it from your post). Run (still from the command line inside the virtual env) dot -Tps C:\\Users\\TUNUGU~1\\AppData\\Local\\Temp\\tmp4dwfnf5z
That should generate a lot of textual output, and no errors.
If any of the above fails I would advise reinstalling graphviz (with conda).

@onomatopeia Thank you very much for the help. I'll get back to you if I get it right.

brew install graphviz
or equivalent should fix this
be careful, it will remove all python link

I get this error. Someone please help. I've already tried doing:
- pip install graphviz
- conda install graphviz
- Downloading graphviz on my system and manually adding its path to environment variable in my script
- Adding downloaded graphviz's bin folder to the environment variable
Nothing worked for me. If someone can please help out would be really helpful. Thanks!
from deepreinforcementlearning.
On Windows 10:
* Run PowerShell as Adnin * `dot -c`
So much time lost but so easy to fix. Thank you so much!
from deepreinforcementlearning.
For Mac, that's how it works for my case:
pydot:
pip3 install pydot
graphviz:
(note it doesn't work if just pip3 install graphviz
, even it's listed under pip3 list
)
This works:
brew install graphviz
, as indicated by them (https://www.graphviz.org/download/) (note you might need to install brew first on you Mac, so copy and paste this line in terminal and run to install brew: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
)
