我一直在做一门关于数据科学和机器学习的课程，其中一节课要求我下载并使用绘图和袖扣。我成功地下载并安装了它们，我也成功地导入了它们。但是在使用iplot的时候，我犯了个错误下面我附上了错误的截图，所以我想知道如何解决这个错误，并使用绘图和袖扣没有任何问题。
我写的代码：
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)
我得到的错误是：
---------------------------------------------------------------------------

最佳答案
执行以下代码时会得到什么？
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)
一切都很好，但你只需要像我想的那样。
在谷歌搜索之后，我找到了possible solution版本-只需降低你的绘图版本：
pip uninstall plotly
pip install plotly==2.7.0
我检查了最新版本的
plotly.offline.plot-它是3.1.1，这个bug也在这里。所以我认为使用plotly
