Hi Nicolas,
the/EO Time Series Viewer Plugin/ is developed by my colleague Benjamin
(CC). The plugin is using the /PyQtGraph /package, which recently
introduced the *'colorama'* dependency. This explains your error:
*ModuleNotFoundError: No module named 'colorama' *
The plugin tries to avoid external package installation by shipping
everything it needs with the plugin, but for now, you need to work
around this, by installing the *'colorama'* package via PIP using the
OSGeo4W shell.
Regards
Andreas
