flask - python上传大文件到服务器报错

项目需要，在mac上将打包好的文件（四五百兆）自动上传到web后台，用了两种方式上传，都报了类似的错误，在windows和linux上测试不会报错，但是到了mac打包机上就会报错：
①第一种报错：

Traceback (most recent call last):
  File "my_upload.py", line 61, in <module>
    upload_pack(f)
  File "my_upload.py", line 54, in upload_pack
    r = requests.post(url, form, files=files)
  File "/Library/Python/2.7/site-packages/requests-2.9.1-py2.7.egg/requests/api.py", line 107, in post

    raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', error(32, 'Broken pipe'))

代码：

# -*- coding: UTF-8 -*-
import requests
import json
import sys
reload(sys)
sys.setdefaultencoding("utf-8")
url = 'http://10.242.12.121:9096/auto_upload/'

# config
channel = unicode('test2').encode('utf-8')
form = {'platform': 'Android', 'channel': channel, 'publish_time': '2016-08-01 00:00', 'remarks': 'auto_test', 'code': 'HH'}
files = {'file': ('D3174449.apk', open('D3174449.apk', 'rb'), 'application/octet-stream')}

s = requests.session()
r = s.post(url, form, files=files, timeout=500)
print r.text
# print unicode(json.loads(r.text)).encode('utf-8')
print 'upload_end'

第二种报错：urllib2.URLError: <urlopen error [Errno 32] Broken pipe>

搜索能力有限，去谷歌搜了下没有找到合适的解决办法，或者是理解不够：
