Gyro data is not reflected

[ArusTaimika]

We are trying to estimate the attitude using the IMU of the Madgwick filter.
However, the gyro data is not reflected and the attitude estimation is wrong.
The code used is as follows.
Graphs of the acquired acceleration, gyro, and estimated attitude are also attached.
Can you tell what is causing this?
If it is my mistake, I really apologize.

q = ahrs.filters.Madgwick(gyr = np.array([g]),acc = np.array([a]))
qq= ahrs.common.Quaternion(q.Q[0])
self.euler = qq.to_angles()
