This notebook demonstrates how to read the newer proto-based logs.



In [2]:

    
# Point to where you have logs stored.
logfile = '../python/listops_rlspinn_test_run.log'



In [3]:

    
import sys
sys.path.append('../python')



In [4]:

    
import spinn.util.logging_pb2 as pb
from google.protobuf import text_format

Parsing the logs is pretty simple. Just read the raw text, and use the text_format module.

To load the logs, use the Merge() function.



In [5]:

    
text = open(logfile, 'r').read()
len(text)









    Out[5]:





119552



In [7]:

    
logs = pb.SpinnLog()
parsed = text_format.Merge(text, logs)



In [10]:

    
# When was the first run in this log executed?
# This is the output of time.time() before running the first step.
parsed.header[0].start_time









    Out[10]:





1497416353L



In [12]:

    
print(len(parsed.entries))
parsed.entries[33]
