The interface is based on NumPy. -NumPy implements an efficient multi-dimensional container of generic data and uses strong typing in order to provide fast data processing in Python. The Trace-Cruncher will allow for sophisticated analysis of kernel tracing data via scripts, but it will also opens the door for exposing the kernel tracing data to the instruments provided by the scientific toolkit of Python like MatPlotLib, Stats, Scikit-Learn and even to the nowadays most popular frameworks for Machine Learning like TensorFlow and PyTorch. The Trace-Cruncher is strongly coupled to the KernelShark project and is build on top of the C API of libkshark. +NumPy implements an efficient multi-dimensional container of generic data and uses strong typing in order to provide fast data processing in Python.

After downloading the source code, you just have to run: - sudo make install + > cd trace-cruncher -4. Build the NumPy API itself: + > make - cd path/to/trace-cruncher + > sudo make install - ./np_setup.py build_ext -i +Note that this will automatically download, patch and build the appropriate versions of "trace-cmd / KernelShark" libraries from kernel.org. These third-party libraries will be installed as part of trace-cruncher itself and will not interfere with any existing system-wide installations of trace-cmd and KernelShark. ## Documentation -- 2.20.1
