Way to fix "KeyError: 'CONTENT-LENGTH'" when using Python3.7

[Kamilet]

When using latest version of Python (3.7.4 for now), the following error will occor when uploading images.

File "...\lib\cgi.py", line 220, in parse_multipart
headers['Content-Length'] = pdict['CONTENT-LENGTH']
KeyError: 'CONTENT-LENGTH'

The same problem won't happen in Python 3.6, because 'CONTENT-LENGTH' isn't necessary. But in Python 3.7 it is. I found a way to temporary fix it for Python 3.7.

1. open 'server.py' and add a line under def parse_POST(self):

   def parse_POST(self):
       ctype, pdict = parse_header(self.headers['content-type'])
       pdict['boundary'] = bytes(pdict['boundary'], "utf-8")
       # Added 1 debug line here
       pdict['CONTENT-LENGTH'] = int(self.headers['content-length'])
       if ctype == 'multipart/form-data':
           postvars = parse_multipart(self.rfile, pdict)
       elif ctype == 'application/x-www-form-urlencoded':
           length = int(self.headers['content-length'])
           postvars = parse_qs(
               self.rfile.read(length),
               keep_blank_values=1)
       else:
           postvars = {}
       return postvars

2. Change line id_str = re.sub(r'\W+', '', id_str.decode()) in def do_POST(self):

   def do_POST(self):
       self.log_t()
       form = self.parse_POST()
       self.log_t()
   
       if "id" in form:
           id_str = form["id"][0]
           # Changed 1 line here
           # original line:
           # id_str = re.sub(r'\W+', '', id_str.decode())
           id_str = re.sub(r'\W+', '', id_str())
       else:
           self.ret_result(False)
           return

   Then it's good to go. Successed with: Windows 10, Python 3.7.4 , CUDA 10.1

@Kamilet Can you please advise what server.py file? I search in anaconda folder and there are multiple file with this name? Thanks
