Plotly shows blank graphs in AWS Sagemaker JupyterLab

Troubleshooting Blank Plotly Graphs in AWS Sagemaker JupyterLab

Encountering blank graphs when using Plotly within AWS Sagemaker JupyterLab can be frustrating. This article will guide you through common causes and solutions to get your plots rendering correctly.

1. Check for JavaScript Errors in the Console

The first step is to inspect the browser console for JavaScript errors. These errors can often reveal why your Plotly graph isn’t displaying. Follow these steps:

1. Open the browser’s developer tools (usually by pressing F12).
2. Navigate to the “Console” tab.
3. Check for any errors related to Plotly or your JupyterLab environment.

2. Ensure Plotly is Properly Imported

Make sure you have imported Plotly correctly in your Jupyter notebook. Here’s the standard import statement:

import plotly.graph_objects as go

3. Verify JupyterLab Extensions

Certain JupyterLab extensions might interfere with Plotly rendering. Try disabling any unnecessary extensions to isolate the issue.

4. Use the “plotly.offline” Module for Static HTML

If you are working within a restricted environment where JavaScript execution might be limited, use the “plotly.offline” module to generate static HTML files of your plots. This approach bypasses potential limitations:

import plotly.offline as pyo

import plotly.graph_objects as go

fig = go.Figure(data=[go.Scatter(x=[1, 2, 3], y=[4, 5, 6])])

pyo.plot(fig, filename="my_plot.html")

This will generate an “my_plot.html” file in your notebook’s directory. Open the file in a web browser to view your plot.

5. Restart Kernel and JupyterLab

Sometimes, a simple restart can resolve issues. Restart both the Jupyter kernel and the JupyterLab server.

6. Check JupyterLab Version and Configuration

Ensure that you are using a compatible version of JupyterLab and that your configuration is properly set up. Consult the Plotly documentation and JupyterLab documentation for specific requirements.

Additional Tips

• Check for any conflicting libraries that might be interfering with Plotly.
• Try using a different browser.
• Review the Plotly documentation for any known issues or updates.
• Seek assistance from the AWS SageMaker forums or Plotly community forums if you’re still facing issues.
