Hi,
Unfortunately, I also meet a similar error. My eIQ Portal version is 2.1.30. What I do is importing around 200 pictures, annotating each picture, selecting detection mode(Balanced, NPU), and leaving the rest default. Click on START TRAINING, then nothing happens within 2 hours. I click on STOP and save the current state of model. When clicking on SELECT MODEL at the bottom, I get the network error. To me, it seems eIQ fails to upload annotated pictures for training due to the network error. I tried for several times but with no luck.
