ImportError: cannot import name 'TensorOpParams' from 'cumm.gemm.algospec.core'

Hi, I built cumm from source on Nvidia Jetson nano board, when I import cumm inside python, no errors appear.
But when import TensorOpParams as following: from cumm.gemm.algospec.core import TensorOpParams I got the following error:

Traceback (most recent call last):
File "", line 1, in
File "/home/jetson/build_spconv/spconv3/spconv/spconv/init.py", line 15, in
from . import build as _build

ImportError: cannot import name 'TensorOpParams' from 'cumm.gemm.algospec.core' (/home/jetson/build_spconv/spconv3/cumm/cumm/gemm/algospec/core.py)

Environment：
NVIDIA Jetson Nano Developer Kit  (aarch64)
Python: 3.7.5
cumm: 0.3.0
cuda: 10.2

Please help me!!! Thank you!
