Jupyterlab, matplotlib, dynamic plots – II – external Qt-windows and figure updates from foreground jobs

The work on this post series has been delayed a bit. One of my objectives was to use background jobs to directly redraw or to at least trigger a redrawing of Matplotlib figures with backends like Qt5Agg. By using background jobs I wanted to circumvent a blocking of code execution in other further Juypter notebook cells. This would to e.g. perform data analysis tasks in the foreground whilst long running Python jobs are executed in the background (e.g. jobs for training a ML-algorithm). This challenge… Read More »Jupyterlab, matplotlib, dynamic plots – II – external Qt-windows and figure updates from foreground jobs

Jupyterlab, matplotlib, dynamic plots – I – relevant backends

When we work with Deep Neural Networks on limited HW-resources we must get an overview over CPU- and VRAM-consumption, training progress, change of metrical variables of our network models, etc. Most of us will probably want to see the development of our system- and model-related variables in a graphical way. All of this requires dynamic plots, which are updated periodically and thus display monitored data live. As non-professionals we probably use Python code in standalone Jupyter notebooks or (multiple) Python notebooks in a common Jupyterlab… Read More »Jupyterlab, matplotlib, dynamic plots – I – relevant backends
