Failed to load nodelet [/imu_filter] of type [imu_filter_madgwick/ImuFilterNodelet] even after refreshing the cache Error

[dlee640]

Hello.

I am trying to utilize madgwick filter included in the ros package. However, when I launch vn100_imu.launch, it returns 'failed to load nodelet' error. The topics still publish, but I don't think the node for the filtered data is activated as shown below. How can I address this issue?

Thanks.
