Convert tflite with mask rcnn

[kewin1807]

How can you convert to mask rcnn to tflite model. Thanks

Here is the script I used for the conversion.

Thanks. I will try. Have you use model which can be converted from this script =)

[PINTO0309]

No, I'm a weird, so I'm just enjoying the conversion for now.

i see the error "Invalid tensors 'image_tensor' were found." Can you solve it ??

[kewin1807]

Check failed: array.data_type == array.final_data_type Array "image_tensor" has mis-matching actual and final data types (data_type=uint8, final_data_type=float).
Can you solve it ??

First, you need to change the placeholder in the Python code of the model from UInt8 to Float32. I'll share the code with you when I have time, but I'm pretty busy and I don't have enough time to work, so please wait a bit.

yeah. i fixed it. But when i load the model tflite. i have a problem "Encountered unresolved custom op: Enter.Node number 0 (Enter) failed to prepare."

Can you solve it ?? Thanks

Two days ago, it seems that the mask r-cnn correspondence was committed to the master branch. So, today I tried to regenerate the weight quantization model using the latest Tensorflow. Operation has not been confirmed.

The installation of the Tensorflow v2.1.0 master I built is as follows.

Below is the script of Weight Quantization.

I was able to successfully convert without a custom OP with Tensorflow v2.2.0-rc3 (Tensorflow Lite). If you feel like it, give it a try.
