ValueError: Mime type rendering requires nbformat>=4.2.0 but it is not installed

Plotly is plotting the plot. But it also is showing the above warning.

I tried https://stackoverflow.com/questions/66557543/valueerror-mime-type-rendering-requires-nbformat-4-2-0-but-it-is-not-installed, but no luck.

hi @NotShrirang
Thanks for reporting this. I see you used this code below. Can you please share your data with us so we can replicate the error locally?

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()

Hi,

I have exactly the same error. Plese find the simple code below to reproduce it:

# generate a simple 3D graph
import plotly.graph_objects as go
import numpy as np

vec1 = np.array([1, 2, 3])
vec2 = np.array([2, 3, 4])
vec3 = np.cross(vec1, vec2)

# plot the vectors in 3D

fig = go.Figure(data=[
    go.Scatter3d(x=[0, vec1[0]], y=[0, vec1[1]], z=[0, vec1[2]], marker=dict(size=[5, 12], color='blue')),
    go.Scatter3d(x=[0, vec2[0]], y=[0, vec2[1]], z=[0, vec2[2]], marker=dict(size=[5, 12], color='red')),
    go.Scatter3d(x=[0, vec3[0]], y=[0, vec3[1]], z=[0, vec3[2]], marker=dict(size=[5, 12], color='green'))
])

fig.show()

Attention! I was not able to run on version 5.19, so I installed the version 5.18. It worked, but then I wanted to reproduce the error for you, so I reinstalled the 5.19 and it keeps on working. Maybe there are some depencencies missing in pip package of 5.19?

Hope it helps you to solve the issue!

Thank you @mjustynaPhD . It seems like the issue is solved. If this comes up again, we'll reopen the issue.

Hello, I am getting this same error from plotly 6.1.2. Not getting the issue with 5.18.0, like @mjustynaPhD mentioned.

Not in the dependencies.

plotly.py/pyproject.toml

Lines 36 to 39 in 3da153f

	dependencies = [
	"narwhals>=1.15.1",
	"packaging"
	]

Can this issue be re-opened?
