是否可以在随机采样时只采样与源节点的某个属性值相同的目标节点 #318

问题的背景是希望采样与源节点的某个属性值相同的目标节点。
比如源节点feature1='a'，则希望采样到的节点也是 feature1='a'。

如果使用：
tf_euler.sample_node(
count, node_type, condition=''
)
但似乎condition的内容是不可变的，不能一会儿 condition='feature1 eq a'，一会儿 condition='feature1 eq b'。

如果使用：
tf_euler.sample_node_with_src(
src_nodes, count
)
则需要将 feature1 作为 node_type，在同时要使用 node_type 时又会冲突。
