I am running graphviz inside a jupyter notebook in vs code. Everytime I run a cell that generates a graphviz dot Windows sees the file and opens it in Chrome. It is also displayed inline in the jupyter notebook where I want it. How can I prevent Chrome from opening?
I've tried creating a launch.json as the project didn't have one. This didn't make a difference. I can't find any available configuration settings I can change to prevent Chrome opening.
To open a jupyter notebook or jupyter lab instance without displaying it in the browser, you have to open the jupyter instance on CMD using the following command. (Of course jupyter should be on path to use jupyter commands on cmd)
jupyter notebook --no-browser <path>
and similarly for jupyter lab:
jupyter lab --no-browser <path>
The path is optional, and if you dont add a path it simply open C:\ as your default path.
Really obvious answer. When I transitioned from running the .py file from the command line to the jupyter notebook I didn't comment out the dot.view() (a graphviz call) that displays the result graph. Jupyter will display the results without this. Duh.
I just downloaded Sublime Text 3 for Mac and tried to run print("Hello world!") as a test by clicking on "build".
The output says
/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't find 'main' module in ''
and some other stuff.
I'm using Python 3 for several months now and I know the main differences between Python 2 and Python 3, but I have no idea what that output means.
Hi I also get the same problem in sublime text 3. And I am fixed.
Open command palette and install the install package.
After completed install python3.
And change like build system, syntax and others.
Finally try to print('hello world')
Save the file in .py extension is must otherwise you getting the same error

I'm on a Jupyter notebook using Python3 and trying to plot a tree with code like this:
import xgboost as xgb
from xgboost import plot_tree
plot_tree(model, num_trees=4)
On the last line I get:
ModuleNotFoundError: No module named 'graphviz'
.........
.........
.........
~/anaconda3/envs/python3/lib/python3.6/site-packages/xgboost/plotting.py in to_graphviz(booster, fmap, num_trees, rankdir, yes_color, no_color, **kwargs)
196 from graphviz import Digraph
197 except ImportError:
--> 198 raise ImportError('You must install graphviz to plot tree')
199
200 if not isinstance(booster, (Booster, XGBModel)):
ImportError: You must install graphviz to plot tree
How do I install graphviz so I can see the plot_tree?
You can install and uninstall packages in your environment on notebook instance using following approach :-
On your jupyter instance, go to the "Conda" tab. There you will find
all the conda environments setup.
Select your relevant environment. After you have selected your option, below in the right panel - you will see all the packages currently installed in your currently selected environment, and in the left panel - you will find what all packages are available and can be added into your environment.
From the left panel, select "graphviz" and then install the selected package to your current environment.
Restart the kernel using "Restart Kernel" option under "Kernel" in your notebook.
Alternatively, you may open a new terminal inside the Jupyterhub Notebook and then
Run conda env list to list all the available environments/kernels
Choose the one you wish to use (e.g. python3) and run source activate python3
Now run the desired pip install ... command
Once this is succeeded. Run source deactivate to close the env. And open up the notebook with the kernel and try import the model just installed.
I suddenly have a problem with file main.py .
I am using pycharm with python version 3.6 from anaconda.
I had a full project that run fine and now the 'main.py' became text file.
If I open a new project and name a new python file as 'main' it automatically turn into text file (any other name remains .py file).
What is the problem?

Adding a module (Specifically pymorph) to Spyder (Python IDE)
(13 answers)
Closed 6 years ago.
I have installed numdifftools and it works in Python shell. But in Spyder, I get this error which don't know how to solve!
ImportError: No module named 'numdifftools'
on the IPython console within spyder allows you to use pip. So, in the example, you could do:
[1] !pip install numdifftools
All possible answers :
1.For any libraries that you want to add that aren't included in the default search path of spyder (whatever that is) you need to go into Tools and add a path to EACH library via the PYTHONPATH manager. You'll then need to update the module names list from the same menu and restart spyder before the changes take effect.
2.Find the location of a module in Terminal:
$ python #open python
>>> import numdifftools #import a module
numdifftools #get the location of the package
Copy-paste the module folder to the 'Spyder.app/Contents/Resources/lib/python2.7'
Relaunch Spyder.app
3.Try install from ipython(within spyder) : !pip install numdifftools
