2. Then please run 'nnictl log stderr' to see the error message.
3. You can also use 'ps aux | grep node' to check is there any running rest server process.

1.Check port 51188 is not occupied:

2. Run 'nnictl log stderr' ,It shows,as follws:

from nni.

Those lines are only warning (we will fix this warning later).
Could you run:
nnictl stop
then, nnictl create --config ~/nni/examples/trials/mnist-annotation/config.yml.

If there is still error, please post the content of the following three files:
~/nni/nnictl/log/stderr
~/nni/nnictl/log/stdout
~/nni/experiments//log/nnimanager.log
Thanks.

@QuanluZhang Hi,QuanluZhang.Thanks your reply

• Run 'nnictl stop',it shows,as follows:
  Info: Stoping experiment...
  Info: Experiment is not running...

Then run 'nnictl create --config ~/nni/examples/trials/mnist-annotation/config.yml.',it shows same error as before

Hi, @wenku1992abc, thanks for reporting the issue and providing the logs.

Could you please help confirm if the log you pasted from your ~/nni/experiments//log/nnimanager.log is a complete log?

A normal log contents in ~/nni/experiments//log/nnimanager.log is something like:
[2018-09-17T03:36:53.950Z] INFO Rest server listening on: http://0.0.0.0:51188
[2018-09-17T03:36:56.773Z] INFO GET: /check-status: body:
{}
[2018-09-17T03:37:03.802Z] INFO GET: /trial-jobs: body:
{}
....................................................
....................................................

if the log from ~/nni/experiments//log/nnimanager.log is a complete one, could you also check if port 51188 is opened on your machine's firewall?

If still have issue, feel free to let us know. Thanks.

from nni.

@yds05 My pleasure!
1.Yes, I checked it again! I am sure log from ~/nni/experiments//log/nnimanager.log is a complete one!

2.According to command 'rpm -qa|grep iptables' in linux, I checked if my machine installed firewall or not.The results is that it has no firewall

from nni.

@QuanluZhang @yds05 May be my problem is the same as this issue,#85 (comment)
my python is also installed with anaconda

from nni.

@wenku1992abc Yes, probably it's related to that issue caused by python installed via anaconda. We will fully test nni on anaconda python soon, and let you know if we have any conclusion/solution. Thanks!

from nni.

@wenku1992abc - had you verified whether the resolution works for you? the support had been released in Sept 28.

from nni.

I'm closing the item as the fix had been released, @wenku1992abc please feel free to reopen the issue if it still not work for you, thanks a lot.

@scarlett2018 Hi,I use new nni source code to install nnictl,after installed
