[Installation]: Failed to install vllm-ascend from source

[tongtong0613]

env:

PTA: 7.1.RC1.B020
CANN: 8.2.RC1.B020

install command:

export COMPILE_CUSTOM_KERNELS=1
python setup.py install

error message:

Function AscendcCompiler at line 98, Command excution failed, the returnCode is non-zero!
Output of ascend_compiler: /home/vllm-ascend/csrc/kernels/pos_encoding_kernels.cpp:357:9: error: use of undeclared identifier 'rope_custom_true_half'; did you mean 'rope_custom_true___cce_half'?

But when I use CANN 8.1.RC1.B080 , all works. Could you please help me take a look at this issue? Thank you very much.

Thanks for feedback, this is caused by CANN breaking change, we will also sync this info to CANN team.
