Description
I installed apex as pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" git+https://github.com/NVIDIA/apex
I'm running python -m apex.pyprof.parse net.sql > net.dict and am getting an error:
File "/miniconda/lib/python3.7/site-packages/apex/pyprof/parse/__main__.py", line 7, in <module>
raise e
File "/miniconda/lib/python3.7/site-packages/apex/pyprof/parse/__main__.py", line 4, in <module>
from .parse import main
File "/miniconda/lib/python3.7/site-packages/apex/pyprof/parse/parse.py", line 12, in <module>
from .kernel import Kernel
File "/miniconda/lib/python3.7/site-packages/apex/pyprof/parse/kernel.py", line 1, in <module>
import cxxfilt, struct, binascii
ModuleNotFoundError: No module named 'cxxfilt'
Maybe cxxfilt somewhere not mentioned as dependency and pip doesn't install it?

Research direction
Start by running python -m apex.pyprof.parse net.sql and inspect the import in apex/pyprof/parse/kernel.py. Check how the Apex package declares dependencies, then verify that a fresh installation provides cxxfilt and that the parser command completes without the reported ModuleNotFoundError.
