Hi Alex,
<div><br>
</div>
<div>Many thanks for your reply. I have another question. When I first installed mini-non, I’ve checked “nfd-status”, it seemed nfd works well at that time. However, now I found that nfd didn’t work and I’ve tried “nfd-start”. It gave me an error below. I wonder
how to solve the problem of nfd. Thanks a lot!</div>

Good morning,</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt;">
I believe this is an issue with the nfdc helper code not handling the returned output for "face-updated" which is not treated as a failure internally in nfdc, we had observed this prior and noted it did not seem to be causing issues. I will try and push an
update ASAP as I believe this has caused confusion multiple times and I was able to find the apparent cause. However, I am reasonably confident that you are safe to ignore it until then.<br>

<div style="direction: ltr;"> </div>
<div style="font-size: 11pt;">Hi all,<br>
<br>
I met an error when building an example to run nlsr on minindn. At last nlsr indeed converges. But there’re two faces fail to register before. I’ve attached the log below.<br>
