Python pcl has no attribute from_array

I was trying to run the example on this page: https://github.com/strawlab/python-pcl/blob/master/examples/example.py I get the error : AttributeError: type object 'PointCloud' has no attribute 'from_array' on line 49. Also, i cant import few modules like pcl.pcl_visualization and pcl.PointCloud_PointXYZRGB() . Anybody knows how do i slove these issues?

Thanks

You should make sure you aren't running PyPCL by accident. This is an alternate python to PCL binding that import pcl can map to. One way to check this is to run this snippet:

class_names = dict([(name, cls) for name, cls in pcl.__dict__.items() if isinstance(cls, type)])
for name, cls in class_names.items():
    print(name)

This will give you a list of classes in the module. If there are two (PointCloud, Quaternion), you likely have PyPCL installed and should uninstall that one. The list of classes in python-pcl returned should look something like this:

PointCloud
PointCloud_PointXYZI
PointCloud_PointXYZRGB
PointCloud_PointXYZRGBA
Vertices
PointCloud_PointWithViewpoint
PointCloud_Normal
PointCloud_PointNormal

Alternatively, if you are in a virtual environment you can run pipenv graph to look for this issue. Or:

pip list
