29.2. METplotpy Upgrade Instructions

Note

In June 2025, Plotly made significant updates to the kaleido package with the 1.0.0 release by removing Google Chrome code. Now, users will need to have Google Chrome installed in directories specified in this Plotly documentation (based on operating system): https://plotly.com/python/static-image-export/

The METplotpy code downloads Chrome at runtime by invoking the kaleido.get_chrome_sync() method call.

If users do not wish to have Chrome downloaded at run time and already have Chrome installed in one of the expected locations (specified in the Plotly link above), then the PRE_LOAD_CHROME environment variable will need to be set to ‘True’ (case insensitive string).
