Neural network did not converge

[Sondr11]

Hi
I made a training model for 1000 samples including both male and female fetuses. However R=0.488
I advance the training model with more samples (2087 samples, including both male and female fetuses) to improve R. However, I get the following error:
Loading sample S200042604_L01_23 | 0/2087 remaining ...
Creating training frame ...
Remaining training features after 'NA' filtering: 23738

Neural network did not converge. Re-run and decrease --hidden or optimize --nfeat. Alternatively, use --olm.
Can someone tell me the cause and how to fix it?
Thank you

Hi.
I used --olm, model train sussces. Then I used predict for FF and PREFACE and I have error.
I increase and decrease --nfeat 45, 55, 80 but I received error same in repeat 8/10; 5/10; 3/10.
what should i do next step to fix the error
Thank you
