I have Anaconda 3.7 installed on Windows. It works in Jupyter but not in Spyder. This code:
import holoviews as hv
import pandas as pd
import numpy as np
output_notebook ()
flora = pd.read_csv ('iris.csv')
hv.extension('bokeh')
frequencies, edges = np.histogram(flora['petal width'], bins = 5)
print(frequencies, edges)
hv.Histogram(frequencies, edges, label = 'Histogram')
returns only values:
[49 8 41 29 23] [0.1 0.58 1.06 1.54 2.02 2.5 ]
WARNING:root:Histogram: Histogram edges should be supplied as a tuple along with the values, passing the edges will be deprecated in holoviews 2.0.
Is it possible to see histogram in Spyder?
(Spyder maintainer here) Holoviews produces content to be rendered in a web browser and Spyder consoles are not able to display that content at the moment, sorry.
