使用python从tensorflow日志中手动读取最后一个值

import re

log_file = open('tensorflow.log', 'r')

log_content = log_file.read()

pattern = r'INFO:tensorflow:.*?(\d+\.\d+)$'
match = re.findall(pattern, log_content, re.MULTILINE)[-1]

print(match)

import re

log_file = open('tensorflow.log', 'r')
log_content = log_file.read()

pattern = r'INFO:tensorflow:.*?(\d+\.\d+)$'
match = re.findall(pattern, log_content, re.MULTILINE)[-1]

print(match)
