  • Closing the web application server may cause an error message to appear.

Time Tagger with Python

Supported Python versions are 2.7, 3.5, 3.6, 3.7, 3.8, 3.9.

  • Install NumPy (e.g. pip install numpy), which is required for the Time Tagger libraries.

  • The Python libraries are installed in your default Python search path: /usr/lib/pythonX.Y/dist-packages/ or /usr/lib64/pythonX.Y/site-packages/.

  • The examples can be found within the /usr/lib/timetagger/examples/python/ folder.

Time Tagger with C++

  • The examples can be found within the /usr/lib/timetagger/examples/cpp/ folder.

  • The header files can be found within the /usr/include/timetagger/ folder (-I /usr/include/timetagger).

  • The assembly shall be linked with /usr/lib/libTimeTagger.so (-l TimeTagger).

General remark

Please contact us in case you have any questions or comments about the Ubuntu or CentOS package and/or the API for the Time Tagger.

The C++ interface will likely also work on other distributions out of the box. The source of the Python wrapper _TimeTagger.cxx is provided in /usr/lib64/pythonX.Y/site-packages/. For building the wrapper, the GNU C++ compiler and the development headers of Python and numpy need to be installed. The resulting _TimeTagger.so and the high-level wrapper TimeTagger.py relay the Time Tagger C++ interface to Python.
