3D unet: Problem with Section 5.4, cannot download model as bioImage

[jing00011]

Hi, I am trying out the 3D unet using the provided sample data (the mitochondria electron microscope image provided in the link). I finished the training and wanted to download the model as bioImage Model zoo to be used in FIJI in section 5.4. However, I keep getting this error message and have no idea what it's saying...

I am using OS: iOS and Chrome, would truly appreciate any help on this! Thank you !!

Hi @jing00011

Thank you! To confirm, is this the output of section 5.4? @mariana-gferreira could you please try to reproduce it?

[jinxsfe]

I also meet same problem

Hi,

This error is due to the calibration voxel values given for the example image.
Replace the default values with 1 and you will be able to save the model.

Please be aware that this will result in the example image being uncalibrated and the pixel size values in the rdf.yaml being 1. These can be edited for the correct values after the model has been exported.

I had replace but still can not be save for model, please seehttps://github.com/HenriquesLab/DL4MicEverywhere/issues/25

[jinxsfe]

even I change the pixel size
