I have found this problem in the community, but the symptoms are different from mine: https://discuss.nebula-graph.com.cn/t/topic/6736
When using Python to connect to Nebula running on a Docker on a virtual machine, an error occurs. The program is as follows:
from nebula3.mclient import MetaCache, HostAddr
from nebula3.sclient.GraphStorageClient import GraphStorageClient
# the metad servers's address
meta_cache = MetaCache([('192.168.120.173', 9559)],50000)
# option 1 metad usually discover the storage address automatically
graph_storage_client = GraphStorageClient(meta_cache)
# option 2 manually specify the storage address
storage_addrs = [HostAddr(host='192.168.120.173', port=9779)]
graph_storage_client = GraphStorageClient(meta_cache, storage_addrs)
resp = graph_storage_client.scan_vertex(
space_name='test',
tag_name='test')
while resp.has_next():
result = resp.next()
for vertex_data in result:
print(vertex_data)
