我试图在Visual Studio代码中打印一个plotly plot,并捕获了此错误:
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)

386 "Mime type rendering requires nbformat>=4.2.0 but it is not installed"
387 )
ValueError: Mime type rendering requires nbformat>=4.2.0 but it is not installed
我使用的代码:
import plotly.graph_objects as go
from plotly.subplots import make_subplots
import plotly.express as px
df = df[df['Data']>0]
df['Timestamp'] = pd.to_datetime(df['Timestamp'])
df = df[(df['Id'] ==1)|(df['Id'] ==6)]
dfp = pd.pivot_table(df,
values='Data',
index=['Timestamp'],
columns=['Id'],
)
nrows = len(dfp.columns)
fig = make_subplots(rows=nrows,
cols=1,
subplot_titles=['Id '+str(c) for c in dfp.columns])
# add traces
x = 1
for i, col in enumerate(dfp.columns):
fig.add_trace(go.Scatter(x=dfp.index, y=dfp[col].values,
name = 'Id '+str(col),
mode = 'lines',
),
row=i+1,
col=1)
fig.update_layout(height=nrows*500)
fig.show()
我在GitHub和this question on stackoverflow上尝试了控制台中的pip install nbformat
,但没有成功。
但是,代码似乎可以在删除最后2行的情况下运行:
fig.update_layout(height=nrows*500)
fig.show()
4条答案
按热度按时间crcmnpdw1#
方法1
重新安装ipykernel通过
方法2

1.安装这个。
1.重新启动内核。
1.大坝肯定会起作用的!

对于那些使用conda的人来说,这对我很有效:
验证conda环境的名称:
conda info --envs
假设它是“myenv”,继续:
conda activate myenv
conda install nbformat
然后重新启动内核。

我也遇到了这个问题。在我的例子中,我只安装了
ipykernel
,但是最好安装jupyter
元包。参考:https://code.visualstudio.com/docs/datascience/jupyter-notebooks
