我正试图通过SSH启动dask群集,但遇到了如下奇怪的错误:
Exception in thread Thread-6:
Traceback (most recent call last):

我这样启动集群:
$ dask-ssh --ssh-private-key ~/.ssh/cluster_id_rsa \
--hostfile ~/dask-hosts.txt \
--remote-python "~/miniconda3/bin/python3.6"
我的
dask-hosts.txt
localuser@127.0.0.1
remoteuser@10.10.4.200
...
remoteuser@10.10.4.207
我已经检查了ssh设置,我可以使用公钥设置登录到所有节点(密钥是未加密的,以避免出现解密提示)。我错过了什么?
