Evaluation error

When I submitted the algorithm, I got the evaluation error: The algorithm failed on one or more cases.

Hi, The error message is: "The image produced in 'images/head-neck-segmentation' is not valid", Maybe there is not a existing folder "Hi, The error message is: "The image produced in '/output/images/head-neck-segmentation' is not valid", please consider using "os.makedirs(os.path.dirname(self.output_dir), exist_ok=True)" to create the folder before the results saved. Best, Xiangde Luo/Jia Fu.

Hi， I have created "/output/images/head-neck-segmentation" folder in the code, and stdout has "Output written to: /output/images/head-neck-segmentation/099929ff-a67a-4f95-b73e-f704fc185162.mha ". The file prediction is successful, but for some reason, the system still prompts the error message "The image produced in 'images/head-neck-segmentation' is not valid".

How can I solve it?

Hi, Actually, I don't know why, but I will email the support team of the grand challenge for help today.

Best, Xiangde Luo/Jia Fu.

Ok, thank you very much.

We need to improve the error messages there. Your output file was created fine, but please ensure that the datatype of your output is SimpleITK.sitkInt8 or SimpleITK.sitkUInt8.

Thanks， it works.
