是否可以在RHEL7上的特定版本17.03中安装DockerCE？
这里有信息:
这里有Docker 17.03,但只在Docker EE而不是Docker CE
如何测试stderr是非空的::
- name: Check script
shell: . {{ venv_name }}/bin/activate && myscritp.py
args:
chdir: "{{ home }}"
sudo_user: "{{ user }}"
register: test_myscript
- debug: msg='myscritp is Ok'
when: not test_myscript.stderr
所以,如果没有错误,我可以阅读::
TASK: [deploy | debug msg='critp is Ok] *******
ok: [vagrant] => {
"msg": "myscritp is Ok"
}
并且cas stderr中的FATAL错误不为空.
我需要创建一个包含随机布尔值的大型numpy数组,而不需要调用swap.
我的笔记本电脑有8 GB的RAM.创建一个(1200, 2e6)数组需要不到2秒,并使用2.29 GB的RAM:
>>> dd = np.ones((1200, int(2e6)), dtype=bool)
>>> dd.nbytes/1024./1024
2288.818359375
>>> dd.shape
(1200, 2000000)
对于相对较小的(1200, 400e3),np.random.randint仍然相当快,大约需要5秒才能生成458 MB阵列:
db = np.array(np.random.randint(2, size=(int(400e3), 1200)), dtype=bool)
print db.nbytes/1024./1024., 'Mb'
但是如果我将数组的大小增加一倍以(1200, 800e3)达到交换量,那么创建需要大约2.7分钟db;(
cmd = """
import numpy as np
db = np.array(np.random.randint(2, size=(int(800e3), 1200)), dtype=bool)
print db.nbytes/1024./1024., 'Mb'"""
print timeit.Timer(cmd).timeit(1)
使用random.getrandbits时间更长(约8分钟),并且还使用交换:
from random import getrandbits
db = np.array([not getrandbits(1) for x in xrange(int(1200*800e3))], dtype=bool)
使用 np.random.randintfor (1200, …
Pylint抱怨Invalid constant name "myprint" (invalid-name)记录器功能的简写.
# import
from utils import get_logger
LOGFILE = '6_evaluator.log'
myprint = get_logger(LOGFILE)
def main():
# some stuff
myprint('log log')
if __name__ == '__main__':
main()
这可以在不调整pylint配置的情况下完成吗？
如果需要,这里的定义是get_logger:
import logging
import os
def get_logger(logfile):
""" Return a logger that log on stdout and in LOGFILE"""
if os.path.isfile('{}'.format(logfile)):
os.remove('{}'.format(logfile))
logging.basicConfig(filename='{}'.format(logfile), level=logging.INFO)
logger = logging.getLogger('')
logger.addHandler(logging.StreamHandler())
myprint = logger.info
myprint('log file at: {}'.format(logfile))
myprint('Again Hello from logger')
return myprint
