rk toolkit lite2使用/usr/lib的librknn_api.so而不是whl包里面的so

如题，rk toolkit2 lite使用/usr/lib的librknn_api.so而不是whl包里面的so。
比如系统中的/usr/lib/librknn_api.so和librknnrt.so是1.3的，而whl中的so是1.4的，这种时候就会提示在用1.3版的runtime。
如果移除/usr/lib/librknn_api.so和librknnrt.so，则提示

D target set by user is: None
E Catch exception when init runtime!
E Traceback (most recent call last):
  File "/home/zylo117/.local/lib/python3.9/site-packages/rknnlite/api/rknn_lite.py", line 140, in init_runtime

Exception: Can not find dynamic library on RK3588!
Please download the corresponding librknnrt.so from https://github.com/rockchip-linu ... librknn_api/aarch64 and move it to directory /usr/lib/


说明它只认/usr/lib/的lib，whl包里面的so是没用的。。。
