I have multiple Notebook cells where im importing the same libraries.
Is there a way to import these libraries once (like in the very 1st cell) and allow all other cells to use them?
Since my notebook has several cells, each importing the same libraries, i'm starting to see alot of redundancies.
Of course! You can add all your libraries at the very top of your notebook. All of them will be available for use.
import pandas as pd
import numpy as np
import matolotlib.pyplot as plt
import seaborn as sns

Consider you do npm i numjs then you want to do something like
import * as nj from 'numjs'
but it does not quite work like other libraries. Is this the correct import statement or is there some trick?
Whenever I start the Jupyter Interactive window in VS Code (using, ctrl+shift+p), I have to load several libraries that I use like numpy and pandas. Is there any way in which a selected set of libraries could be made to auto import every time the Jupyter Interactive window starts
something like
import numpy as np
import pandas as pd
every time a new interactive window starts
Any way to do the from - import from Python in Reticulate without having to import the whole module?
example: from tensorflow import keras
I know about the solution below, but it imports the whole module anyway...
keras <- import('tensorflow')$keras
I am not sure, but if you are writing your r code in an rmd file, wouldn't you be able to do it directly in a python chunk like this:
python
from ... import ...
I use iPython Notebook for scientific applications and I'm always plotting experimental data sets. The default image rendering and color cycling behavior of the combination of iPython Notebook and Matplotlib is pretty bad, but it's great after the following tweaks.
# ipython notebook specific
%pylab inline
# imports
from matplotlib import pyplot as plt
import matplotlib as mpl
from seaborn.apionly import set_palette
from IPython.display import set_matplotlib_formats
# configure plotting
set_matplotlib_formats('pdf', 'svg')
set_palette('Set1', n_colors=15, desat=None)
mpl.rcParams['figure.figsize']=(12.0,2.0)
I don't want to have to enter these manually in every notebook. How can I have these executed for all notebooks I'll ever create?
You can create Python files in $HOME/.ipython/profile_default/startup/ that contains the code you want executed at startup.
For example, you can create $HOME/.ipython/profile_default/startup/00-init.py:
# imports
from matplotlib import pyplot as plt
import matplotlib as mpl
from seaborn.apionly import set_palette
from IPython.display import set_matplotlib_formats
# configure plotting
set_matplotlib_formats('pdf', 'svg')
set_palette('Set1', n_colors=15, desat=None)
mpl.rcParams['figure.figsize']=(12.0,2.0)
Note that IPython magics are not supported here, so %matplotlib inline won't work. This question deals with making %matplotlib inline the default.
You should be aware that if you change the defaults for your IPython environment, your notebooks may not work on other people's IPython installations.
I tried to use nbconvert > HTML and it returns random bokeh logos
here is my code:
import pandas as pd
from bokeh.plotting import *
output_notebook()
df = pd.DataFrame({'rev':[234,345,657,7]})
df
line(df['rev'],df['rev'], color="red", line_width=2,
title="Archimean", legend="Archimedean")
show()
A small CSS bug made it into 0.5.0 that affects nbconvert output. There is alread a fix checked into master. We will be releasing 0.5.1 early next week.
