On Windows 10/11 (x86-64) with VIVE Tracker 3.0:
Installing via pip install pysurvive makes the sample scripts raise errors at runtime and no tracking data is returned.
Building the latest GitHub source and using the resulting Python bindings works correctly.
Replacing the DLLs from bindings/python/pysurvive/plugins (built locally) into the pip installation’s .../site-packages/pysurvive/plugins fixes the problem immediately.
This indicates the PyPI wheel contains outdated/broken plugin DLLs, while the current GitHub source produces working DLLs.
