plotly_express installs via pip but doesnot import

[nitin0301]

Hi,

I am using Python 3.6.8 in anaconda environment.

pip install plotly_express works.:

BUT I cannot find the module when I do "import plotly_express":

ModuleNotFoundError Traceback (most recent call last)

----> 1 import plotly_express

ModuleNotFoundError: No module named 'plotly_express'

That's quite strange... Can you tell me a bit about your environment? Which version of Python and pip are you on?

[nitin0301]

Python 3.6.8 & pip 19.0.3

[nicolaskruchten]

Thanks, and sorry I missed the Python version you'd already provided at the top there... I'm not sure if it will fix your issue but I've just pushed up version 0.1.1 of plotly_express which requires plotly>=3.7.1 only (and not alongside plotly>=3.6.0). Perhaps installing will work in your environment now?

[nitin0301]

Thanks nicolaskruchten. It is working on my pycharm but not in conda. So, this will work for now.

Hey, hope you are doing well @nitin0301.

Similar Scenario

I had the same issue as you. I went through to try to resolve it, but I actually found a quick workaround for this issue, while a somewhat larger issue is at hand for particular pip paths for some people.

Workaround

Run this line in a cell within your Jupyter Notebook:

!pip install plotly_express

Root Cause

When we ran pip install plotly_express in our CLIs, we downloaded the package in the system's pip tool, and not within anaconda's pip. Even with the consideration of creating an environment, you would get this issue.

After some trial and errors from finding out that upgrading jupyter, system's python, and manually trying to change the .bash_profile's filepath, I got nothing.

Solution

After checking the diff's of the system and jupyterpip list and conda list, I thought:
"why don't I just run the command within the Jupyter Notebook?"

!pip install plotly_express

Ran the following, and it seems to work now.

#Example code from documentation
iris = px.data.iris()
px.scatter(iris, x="sepal_width", y="sepal_length")
#Enjoy the visualization, hopefully :D 

Note: Your Pycharm has an association with system's default pip and python, but not to anaconda's equivalent

Work still needed

Direct the pip and python path's from system/CLI to anaconda's paths.

@nicolaskruchten thoughts?

I am using Python 3.6.8 in anaconda environment.

when you make a new conda env, install pip in it first, otherwise when you pip install something inside the conda env it uses the base anaconda pip file.

Its quite confusing, anaconda should just install pip by default inside environments.

Same error with conda 4.7.12, even in a simple python prompt after conda install -c plotly plotly_express had successfully completed:

ModuleNotFoundError: No module named 'plotly.express'

Looks like we need to specify the plotly express version in order to avoid this:

conda install -c plotly plotly_express==0.4.0

[myounus96]

simply upgrade the plotply

[entzyeung]

!pip install plotly_express

will fix this problem

!pip install plotly_express

thank you

[mqsaud]

!pip install plotly_express did not fix for vs code

[SomKamoji]

same like mqsaud it did not fix for me

[Wrench-wench]

!pip install plotly_express did not fix for vs code

I had the same issue in VS Code on Windows 10, what fixed it for me was I was using Python3.9 installed from the Windows Store. Switching to Python installed by the Python installer solved the import issues.
