Possible Causes of the Error
Before we start troubleshooting, let’s identify some potential causes of the error:

Troubleshooting Steps
Now that we’ve identified the potential causes, let’s walk through the troubleshooting steps:
Step 1: Check Your Plotly Version
Make sure you’re running the latest version of Plotly. You can check your version by running:
import plotly
print(plotly.__version__)
Compare your version with the latest version available on the Plotly website. If you’re running an outdated version, update Plotly using pip:
pip install --upgrade plotly
Step 2: Check for Conflicting Library Versions
Plotly.express relies on other libraries to function correctly. Check if you have conflicting versions of these libraries installed:
- matplotlib
- seaborn
- pandas
- numpy
Use pip to check the versions:
pip show matplotlib seaborn pandas numpy
Compare your versions with the compatible versions listed on the Plotly website. If you find any conflicts, update or downgrade the conflicting libraries accordingly.
Step 3: Check Your Installation
Ensure that you’ve installed Plotly correctly. Try reinstalling Plotly using pip:
pip uninstall plotly
pip install plotly
Also, make sure you’re running the correct Python version (Plotly supports Python 3.7 and above).
Step 4: Check Your Import Statement
Double-check your import statement for any typos:
import plotly.express as px
Make sure you’re using the correct capitalization and spacing.
Step 5: Check for matplotlib Version Conflicts
matplotlib is a crucial dependency for Plotly.express. Ensure you’re running a compatible version of matplotlib:
import matplotlib
print(matplotlib.__version__)
Compare your version with the compatible versions listed on the Plotly website. If you find any conflicts, update or downgrade matplotlib accordingly.
Additional Troubleshooting Steps
If the above steps don’t resolve the issue, try the following:
Step 6: Check Your Environment
Try importing Plotly.express in a fresh Python environment to isolate the issue:
python -m venv myenv
source myenv/bin/activate
pip install plotly
python
import plotly.express as px
If the issue persists, it might be related to your system configuration or other dependencies.
Step 7: Check for Other Dependencies Issues
Plotly.express relies on several other libraries to function correctly. Check if you have any issues with these dependencies:
Library | Compatible Version |
---|---|
numpy | >=1.16.5 |
pandas | >=0.25.3 |
matplotlib | >=3.3.0 |
seaborn | >=0.11.0 |
Update or downgrade these dependencies accordingly if you find any conflicts.
