 The code looks like:

 {{{
 from sys import stdin

 from stem.descriptor import parse_file

 new_micro_digests = set()

 for desc in parse_file(stdin, validate = True):
     new_micro_digests.add(desc.digest)
 }}}

 The stack trace looks like:

 {{{
 $ cat 2017-10-14-17-05-00-micro | ./get_micro_fp.py
 Traceback (most recent call last):
   File "./get_micro_fp.py", line 9, in <module>
     for desc in parse_file(stdin, validate = True):
   File "/Users/dev/stem/stem/descriptor/__init__.py", line 196, in
 parse_file
     initial_position = descriptor_file.tell()
 IOError: [Errno 29] Illegal seek
 }}}
