ANNarchy 4.6.9 released

[Julien Vitay]

ANNarchy 4.6.9 has been released! 

Apart from the usual bug fixes and performance improvements, the main novelty is the tensorboard extension, which allows to keep track of simulations and visualize them with tensorboard. 

Check the manual (https://annarchy.readthedocs.io/en/latest/manual/Logging.html), the API (https://annarchy.readthedocs.io/en/latest/API/Logging.html) and the examples (https://annarchy.readthedocs.io/en/latest/example/BasalGanglia.html, https://annarchy.readthedocs.io/en/latest/example/BayesianOptimization.html)

• The tensorboard extension allows to log various infos and visualize them using tensorboard.
• The API of the convolution extension has slightly changed, check the documentation.
• Changed default behavior from the built-in Izhikevich neuron model from fast spiking to regular spiking.
• PopulationView.rank_from_coordinates and PopulationView.coordinates_from_rank now accept coordinates relative to the geometry of the popview using the local flag.
• Fixed installation on Anaconda distributions. Now works in colab with !pip install ANNarchy.
• Several bug fixes (variable-dependent refractory periods, conditionals of the type “if (t==1)”, etc).
• Improved performance with CUDA.
