matplotlib on CLI #1

Closed lvhengani closed 6 years ago

lvhengani commented 6 years ago

Hi, Thanks you for this wonderful tool. Is is possible to avoid importing Matplotlib and also omitting the imports for any python graphic user interface libraries for command-line interface (CLI) runs?

ACOLITE relies on matplotlib for outputting plots and mapped images. It should however be possible to run just the processing without any figure generation. I added an additional --nogfx option that skips the matplotlib import in the launcher (which was needed to select the Agg backend), and disables any outputs that use matplotlib. This option should be used in addition to --cli as some CLI users may require output plots. For example:

python launch_acolite.py --cli --nogfx --settings=$file

Note that I renamed the acolite.py launcher to _launchacolite.py to avoid an issue with PyInstaller for the binary distribution. Does this update work for you?

Thank you for the update and for coming back to me. I think this will work. I will test and come back to you. I am using ACOLITE in a docker-container and it is a nightmare to use matplotlib in a container. The other reason is when using docker-containers, its best to use minimal memory usage as possible.

Hi I tested and it working fine. Thank you.
