MemoryError: Model buffer memory allocation failed

[QianqianF]

Describe the bug
I am trying to deploy a kmodel that's around 1MB to k210 but the model can't be loaded.

To Reproduce
Steps to reproduce the behavior:

from maix import KPU
kpu = KPU()
kpu.load("/sd/best_model_float32.kmodel")

The kmodel used and the tflite model before conversion are attached

Expected behavior
I expect the model to load without an issue given the spec of k210.

Actual behaviour
I get one of the two errors
