the problems may meet and fix if have to use old "etw_pytorch_utils" version

[utilpotatocat]

Set up problem:
.h file not found and old at_check problems may meet
should fix like the newest author's _ext-src and author's setup.py
turn at_check to at_assert and use "include_dirs=[osp.join(this_dir, _ext_src_root, "include")]" in setup function

etw_pytorch_utils:
do not use git+ to install etw_pytorch_utils , should git clone one to fix it
_torch.six problem may in etw_pytorch_utils:
comment out： “from torch._six import string_classes, int_classes”
and add ：
int_classes = int
string_classes = str

and websocket-client problem may meet ：
because etw_pytorch_utils have viz.py which use visdom,and visdom use websocket-client
and pip may just download newest websocket-client,which has ":=" code (only for python 3.8+)
cound pip install old version websocket-client for python 3.7 to fix
