TypeError: MMPoseInferencer.__init__() got an unexpected keyword argument 'output_heatmaps'

Additional information

1. Expected result

According to the documentation, MMPoseInferencer have a parameter output_heatmaps (here, first "Parameters" block), but the class __init__ doesn't support this parameter.

Also, this parameters was intended to return the heatmap in the results, or only to generate a visualization for it (as the draw_heatmap inference parameter already does)? I'm trying to get only the heatmap image for each keypoint, and I'm a confused about how to do it.

2. Dataset used
   None

3. Possible reason
   Incorrect documentation
