Problem description & steps to reproduce
when run ./llama-cli --version appear error
`./llama-cli --version
CANN error: EE1001: [PID: 753761] 2025-10-17-11:53:32.738.425 The argument is invalid.Reason: rtMemGetInfoEx execute failed, reason=[context pointer null]
Solution: 1.Check the input parameter range of the function. 2.Check the function invocation relationship.
TraceBack (most recent call last):
Check param failed, curCtx can not be null.[FUNC:MemGetInfoEx][FILE:api_impl.cc][LINE:2297]
The argument is invalid.Reason: rtMemGetInfoEx execute failed, reason=[context pointer null]
get memory information failed, runtime result = 107002[FUNC:ReportCallError][FILE:log_inner.cpp][LINE:161]
ctx is NULL![FUNC:GetDevErrMsg][FILE:api_impl.cc][LINE:5372]
The argument is invalid.Reason: rtGetDevMsg execute failed, reason=[context pointer null]
