Getting a " NameError: name '_imp' is not defined " while try to plot plotly chart on streamlit window

I was trying to plot two variables dataframe in a chart using plotly graph objects. but when I ran it. it is giving _imp is not defined. I searched everywhere but I didn’t get my answer.

code:

        fig = go.Figure()

        fig.add_trace(go.Scatter(x=df['Cumulated_T']/3600,
                                y = df['Capacity'],
                                line = dict(color='purple',width=3))
                     )
        fig.update_layout(
                           title = 'Battery Discharge Capacity',
                           xaxis_title = 'Working time [hours]',
                           yaxis_title = 'Battery Capacity in Ahr')
        st.plotly_chart(fig)

Error:

Hi @Annamalaisaravanan , thanks for submitting your issue! Looking at the error, it looks unrelated to streamlit. Have you tried running it in a separate python console and just trying that?
From my google search, I can’t seem to find anything substantial either :confused:

Hi @willhuang,
Thanks. I’ll try and let you know. is it because any incompatibility b/w stream lit and plotly version?

Hi @Annamalaisaravanan , I think we just upgraded our plotly version 14 days ago (Update plotly.js version (#5022) · streamlit/streamlit@bd406d0 · GitHub). This will come out in the official latest release which should be later this week on thursday.

If you want to test it out with the latest plotly upgrade, you can try it by installing the streamlit nightly (Pre-release features - Streamlit Docs)
