tvm android_rpc_test.py执行报错解决

执行 python3 tests/android_rpc_test.py

报错：

Run CPU test ...

解决方法：

把cpu_lib.tar改为cpu_lib.so；并且在export_library添加ndk.create_shared，如下：

path_dso_cpu = temp.relpath("cpu_lib.so")

f.export_library(path_dso_cpu, ndk.create_shared)

原因：

没有添加ndk.create_shared，使用默认的编译器，在android上不能跑
