我正试图确定轨迹上的路径。我有一条长点的轨迹
这是我的密码:
def clustersDBSCAN(data):
from sklearn.cluster import DBSCAN
a=data
coords = a['Long']
coords['Lat'] = a['Lat']
coords = coords.to_numpy(coords)
kms_per_radian = 6371.0088
epsilon = 0.02 / kms_per_radian
db = DBSCAN(eps=epsilon, min_samples=1, algorithm='ball_tree', metric='haversine').fit(np.radians(coords))
cluster_labels = db.labels_
a['clusters']=cluster_labels
return a
我的enter是一个带有一些其他变量的数据帧。当我运行过程时,会出现以下错误:
Traceback (most recent call last):
File "<ipython-input-160-1bb326319131>", line 19, in <module>
TestEtude1 = clustersDBSCAN(TestEtude1)
File "<ipython-input-160-1bb326319131>", line 14, in clustersDBSCAN
db = DBSCAN(eps=epsilon, min_samples=1, algorithm='ball_tree', metric='haversine').fit(np.radians(coords))
TypeError: loop of ufunc does not support argument 0 of type float which has no callable radians method
编辑:
我的数据如下所示:
Lat Long Type de point
136701 53.87030526540526 7.305133353275677 1
136702 53.870307858385225 7.305140443133933 0

点1的类型表示轨迹的原点,点2的类型表示轨迹的终点。在1和2之间,有0类型的点,它们是按时间点排序的中间点
数据的特征包括纬度和经度。因为它是一个数据帧,所以在本例中,您可以切片到要用于执行集群的功能
查看代码,可以看出所传递的功能不正确,您可以执行以下操作:
在
fit()
中用np.radians(data[["Lat","Long"]])
替换np.radians(coords)
,它应该可以工作相关问题 更多 >
