From the ERROR log, it shows that the submitted TFLite model had been putting into the evaluation device (The format of folder structure is correct).
But, on the device side, something unexpected happens. Please help to check if TF 1.15.0 is used for the conversion from .pb to .tflite. (listed in

4. Export a TFLite model (with Tensorflow 1.15.0) of your solution and add it to the abovementioned ZIP archive; we will run this model to perform the evaluation on the target platform, MediaTek Dimensity 1000+.

Please create the TFLite which has input shape [1, 544, 960, 4] and output shape [1, 1088, 1920, 3]
The runtime of your TFLite model will be automatically evaluated on MediaTek Dimensity 1000+ platform and updated in the leaderboard of runtime per image [s].
Participants are welcome to use our tutorial codes to export TFLite models.

or directly apply our conversion script (w/ TF 1.15.0 installed) in

Thanks for your reply. But actually I used TF 1.15.0 to convert the conversion from .pb to .tflite and also, I used the conversion script (from .ckpt to .pb & from .pb to .tflite) that you released in So that is what really puzzled me。

In addition, this tflite file can run on my own smartphone(using AI Benchmark),So I wonder whether you can release the

Hi rhwang ,

Could you post your submitted time and submission ID, so that we could check your model in detail.
Thank you.
