Let's visually inspect the external frame of the QuadTree index. We'll then plot the spatial dataframe to ensure the spatial index encompasses all our features: midx = gis.map("United States") midx midx.center = [39, -98] midx.basemap.basemap = 'gray-vector' # draw the spatial index ...
However, we can pass any integer argument to display the same number of rows from the data frame. The output of the above command would be: sepal length (cm) sepal width (cm) petal length (cm) petal width (cm) 0 5.1 3.5 1.4 0.2 1 4.9 3.0 1.4 0.2 2 4.7 3.2 1.3 0.2 3 4.6 3.1...
Similar toPyVector, PyCall also provides a typePyDict(a subclass ofAssociation) that implements a no-copy wrapper around a Python dictionary (or any object implementing the mapping protocol). Just usePyDictas the return type of apycallreturning a dictionary, or callPyDict(o::PyObject)on a ...
A vector or an embedding is a numerical representation of text data. For example, using an embedding framework, text like ‘name’ can be transformed into a numerical representation Semantic search consists of retrieving texts whose meaning matches a search query. For example, if your search query...
