I used the following code to do plot a figure in python, but it does return anything at all. Does anyboday know why this happend? And how can I fix it? Thank you.
import plotly.express as px
df = px.data.iris()
fig = px.scatter(df, x="sepal_width", y="sepal_length", color="species")
fig.show()
If you're running this in a Jupyter Notebook, then you need to install the extensions.
See the following from the repo's readme:
For use in the Jupyter Notebook, install the notebook and ipywidgets
packages using pip...
pip install "notebook>=5.3" "ipywidgets==7.5"
or conda.
conda install "notebook>=5.3" "ipywidgets=7.5"
For use in JupyterLab, install the jupyterlab and ipywidgets
packages using pip...
pip install jupyterlab "ipywidgets==7.5"
or conda.
conda install jupyterlab "ipywidgets=7.5"
Then run the following commands to install the required JupyterLab extensions (note that this will require node to be installed):
# Basic JupyterLab renderer support
jupyter labextension install [email protected]
# OPTIONAL: Jupyter widgets extension for FigureWidget support
jupyter labextension install @jupyter-widgets/jupyterlab-manager [email protected]
Please check out our Troubleshooting guide if you run into any problems with JupyterLab.
