问题
Scipy has an excelent spatial analysis pack which includes a K-dimensional tree. I am attempting to use the query function and it is returning this error:
ValueError: x must consist of vectors of length 6 but has shape (2,)
Does anyone know what this error is referring to?
From some google searching I have discovered it has this general format:
raise ValueError("x must consist of vectors of length %d but has shape %s" % (self.m, np.shape(x)))
I believe This is the source code.
回答1:
Figured it out:
This particular value error is referencing the length of the array used to build the KD Tree.
The %d value represents the length of the array used to build the KD tree, and the %s value represents the length of the array like object you are using to query.
In my example the %d value was 6 because I had built a 6 dimensional array.
The %s value was 2 because I had only fed it two coordinates: (X,Y) to query.
My error was that I had accidentally included 4 extra fields when building the KD tree. Now that both values are 2, all works as expected.
