plotly express error: cannot import name 'qualitative'

[nhohung]

Hi,

I'm trying to create a Choropleth map using plotly express. However when importing plotly express, I got an error:
code:
import plotly.express as px
error:

---------------------------------------------------------------------------

ImportError: cannot import name 'qualitative'

This issue is different from issue plotly #26793, plotly express #1672 and #123.

I have tried uninstalling plotly, both via pip and conda and reinstalling plotly version 4 as suggested at the main github page, pypi and plotly. However there is no success.

Just to be clear, I run an environment on cloud.IBM.com notebook, python 3.6, built-in plotly 3.6.1.

I have no further clue how to fix this, please provide some help. Any suggestion is appreciated.

Thanks,
Hung

Hum, it seems to be something related to your environment? Could you try the import in a completely fresh environment to diagnose? Also, if you're using the "built-in plotly 3.6.1", version 3.6.1 did not include plotly.express, you need a version greater than >= 4 for this. For further help, please provide the list of packages installed in your environment.

Hi Emmanuelle,

Thanks for your response.

I am aware that I need plotly version higher than 4. In my previous post, I have tried uninstalled plotly and reinstalled the newest version (4.5.4) but it didn't help.

Today when I basically redo everything, it works! My best guess is because the instance is restarted.

For those who have the same problem, this is exactly what I run at the beginning of my notebook:

! pip freeze   # optional: this is to check current installed package
! pip install plotly --upgrade   # this to update plotly to latest version, at the time of this post: 4.5.4
! pip install plotly   # might be unnecessary, but I did this
import plotly.express as xp   # now it works

Therefore, I'm closing the issue. Thanks for your help.

[emmanuelle]

great, glad to see you could solve the problem!

[kenaitian]

i did what @nhohung suggested above and which worked for him but having to restart the kernel from the IBM Watson Notebook then fixed the issue.

[shubendu]

It worked for me thank you so much

THE BEST WAY
You can install it in command line via pip:
pip install plotly
Or Install specific version:
pip install "plotly==4.5.2"
