Hi @zh794390558! This looks like a problem with IPv4/IPv6 support.
@nfelt, you did a lot of work in this space in #1449: mind taking a look
at this?

[nfelt]

@zh794390558 please provide the rest of the relevant information from our issue template, in particular:

• OS Platform and version (e.g., Linux Ubuntu 16.04)
• Python version (e.g. 2.7, 3.5)

Can you also provide the output of

python -c 'import socket; import pprint; pprint.pprint({x: getattr(socket, x) for x in socket.__all__})'
python -c 'import socket; print(socket.getaddrinfo(None, 8012, socket.AF_UNSPEC, socket.SOCK_STREAM, socket.IPPROTO_TCP, socket.AI_PASSIVE))'

[nfelt]

Thanks. So I guess we can't really reply on socket.has_ipv6 because in both cases apparently you still can't use an IPv6 loopback address.

For now, the workaround would be to explicitly pass either --host localhost (to serve on the loopback IP address, in your case most likely 127.0.0.1) or --host 0.0.0.0 (to serve on all IPv4 addresses).

We might be able to fix this by falling back to IPv4 if we get an address family unsupported error, though it will be a pain to do that in the current code.

[svobora]

@nfelt Previously TensorBoard worked fined, now I've build TF with CUDA 10 support for Ubuntu 18.04 and Python 3.6 and TB stopped working.

The host option solved the problem for me.

[nfelt]

If you updated your TensorFlow installation, it would typically pull in a newer version of TensorBoard. Release 1.11 fixed some problems with IPv6 but it may have exposed this problem for certain platform configurations where the python socket module claims to support IPv6 but the underlying system won't actually let you bind to the IPv6 wildcard.

[Ramlinbird]

May be you can specify the --host parameter as your machine's hostname, I tried and it works.

[liutongxuan]

Notes: if use --host localhost , can't remotely access the ip:port in website. Use --host <ip> would be a better choice.
