How to run?

[ankushnag14]

I copied the code as below and to understand what this project is doing. It returned with 0 errors when I run it. But how do I view the plot.

import pandas as pd import numpy as np import os from ipywidgets import Image, Layout, HBox, VBox import plotly.graph_objs as go from ipywidgets import HTML import plotly.plotly as py

cars_df = pd.read_csv('data/cars/cars.csv', usecols=['City mpg', 'Fuel Type', 'Horsepower', 'Model Year', 'Torque', 'Hybrid', 'ID']) cars_df.sample(5)

image_data = {} for img_filename in os.listdir('data/cars/images'): model_year = img_filename.split('.')[0] with open("data/cars/images/2009_Audi_A3.jpg", "rb") as f: b = f.read() image_data[model_year] = b

Image(value=image_data['2012_Chevrolet_Camaro_Coupe'])

fig = go.FigureWidget( data=[ dict( type='scattergl', x=cars_df['Torque'], y=cars_df['City mpg'], mode='markers', ) ], )

fig.layout.title = 'Torque and Fuel Efficience' fig.layout.titlefont.size = 22 fig.layout.titlefont.family = 'Rockwell' fig.layout.xaxis.title = 'Torque (foot-pounds)' fig.layout.yaxis.title = 'City MPG' scatter = fig.data[0] N = len(cars_df) scatter.x = scatter.x + np.random.rand(N) * 10 scatter.y = scatter.y + np.random.rand(N) * 1 scatter.opacity = 0.2 fig.layout.hovermode = 'closest' # Set to 'closest'

contour = fig.add_histogram2dcontour( x=scatter.x, y=scatter.y) contour.colorscale = 'Hot' contour.reversescale = True

contour.hoverinfo = 'skip'

scatter.text = cars_df['ID'] scatter.hoverinfo = 'text'

details = HTML()

def hover_fn(trace, points, state): ind = points.point_inds[0] details.value = cars_df.iloc[ind].to_frame().to_html()

scatter.on_hover(hover_fn)

image_widget = Image( value=image_data['2012_Chevrolet_Camaro_Coupe'], layout=Layout(height='252px', width='400px') )

def hover_fn(trace, points, state): ind = points.point_inds[0]

# Update details HTML widget
details.value = cars_df.iloc[ind].to_frame().to_html()

# Update image widget
model_year = cars_df['Model Year'][ind].replace(' ', '_')
image_widget.value = image_data[model_year]

scatter.on_hover(hover_fn)

VBox([fig, HBox([image_widget, details])])

Hi @ankushnag14, thanks for letting me know.

Did you run the code in the classic Jupyter Notebook or in JupyterLab?

Did you follow the full set of installation instructions at https://github.com/plotly/plotly.py? There are a bunch of versions that have to line up, especially if you're working in JupyterLab.

Thanks!

I was using JupyterLab. I probably didn't have things configured correctly.
