问题
I have been doing a course on data science and machine learning and in one of the lesson, it asked me to download and use plotly and cufflinks. I downloaded and installed them successfully, I have imported them successfully as well. But while trying to use them using iplot, it's giving me an error. Below I have attached screenshots of the error so I want to know how to solve this error and use plotly and cufflinks without any issue.
The code that I wrote:
import pandas as pd
import numpy as np
%matplotlib inline
from plotly import __version__
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
print(__version__)
init_notebook_mode(connected=True)
cf.go_offline()
df = pd.DataFrame(np.random.randn(100,4),columns='A B C D'.split())
df.iplot(kind='scatter',x='A',y='B',mode='markers',size=10)
The error that I get:

回答1:
What you would get when executed following code?
import plotly
import plotly.plotly as py
import plotly.graph_objs as go
import numpy as np
import pandas as pd
import numpy as np
%matplotlib inline
from plotly import __version__
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import cufflinks as cf
print(__version__)
init_notebook_mode(connected=True)
cf.go_offline()
df = pd.DataFrame(np.random.randn(100,4),columns='A B C D'.split())
trace = go.Scatter(x = df['A'], y = df['B'], mode = 'markers')
data = [trace]
fig = go.Figure(data=data)
plotly.offline.plot(fig)
With plotly.offline.plot everything work fine but you need only plotly.plotly.iplot as I think.
After googling I found the possible solution to that - just downgrade your plotly version:
pip uninstall plotly
pip install plotly==2.7.0
I checked the latest version plotly - it is 3.1.1 and this bug also is here. So I am suppose that using version plotly<3.0.0 can solve your problem
回答2:
Updated solution as of 2019:
This is an error that happens if you have cufflinks version 0.13 or older which was not compatible with plotly 3.0. This may happen because you installed from conda or another source and not with pip.
To solve it, run:
pip install cufflinks --upgrade
回答3:
To sum up as told by @Idodo you have to write the following lines of code in your "Anaconda Prompt" please open this by selecting as an administrator.
for the plotly library
conda install -c plotly plotly
for the cufflinks library
conda install -c conda-forge python-cufflinks
then upgrade the cufflinks
pip install cufflinks --upgrade
