Wie man numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject behebt

Lösung

Du verwendest eine NumPy-Version, die nicht mit der von dir verwendeten pandas-Version kompatibel ist. Um dies zu beheben, musst du numpy auf eine Version herabstufen, die mit deiner pandas-Version kompatibel ist.

downgrade_numpy.sh

pip install numpy==1.26.4

pip install numpy==1.26.4

wird das Problem meistens beheben. Wenn das nicht funktioniert, versuche, eine ältere pandas-Version oder eine neuere Python-Version zusammen mit aktuellen Versionen von NumPy und pandas zu verwenden.
