python-api连接DolphinDB服务器报错

Question

查入数据库报错，代码如下

import dolphindb as ddb
s = ddb.session()
s.connect("localhost", 24115,"admin", "123456")
x = s.loadTable(tableName="pt",dbPath="dfs://db1")

下面的错误信息

C:\Users\test\anaconda3\lib\site-packages\dolphindb\session.py:69: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray
  return self.cpp.run(script, *args)

为什么

Answer 1

执行以下语句时会报此警告：

x = s.loadTable(tableName="pt",dbPath="dfs://db1")

警告是由高版本的numpy引起的。不影响正常功能，降级numpy版本即可取消。
