我想激活elasticsearch的日志.

当我运行elasticsearch二进制文件时,我意识到我的日志记录存在问题:配置无法加载!

这是输出:

~ $ sudo /usr/share/elasticsearch/bin/elasticsearch

我在Stack Exchange上的一些问题中看到,限制可以是每15分钟的请求数量的函数,并且还取决于算法的复杂性,除了这不是一个复杂的.

所以我使用这段代码:

import tweepy
import sqlite3
import time

db = sqlite3.connect('data/MyDB.db')

# Get a cursor object
cursor = db.cursor()
cursor.execute('''CREATE TABLE IF NOT EXISTS MyTable(id INTEGER PRIMARY KEY, name TEXT, geo TEXT, image TEXT, source TEXT, timestamp TEXT, text TEXT, rt INTEGER)''')
db.commit()

consumer_key = ""
consumer_secret = ""
key = ""
secret = ""

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(key, secret)

api = tweepy.API(auth)

search = "#MyHashtag"

for tweet in tweepy.Cursor(api.search,
                           q=search,
                           include_entities=True).items():
    while True:
        try:
            cursor.execute('''INSERT INTO MyTable(name, …

我在json文件中有一些日期,我正在搜索与今天日期相对应的日期:

import  os
import time
from datetime import datetime
from pytz import timezone

input_file  = file(FILE, "r")
j = json.loads(input_file.read().decode("utf-8-sig"))

os.environ['TZ'] = 'CET'

for item in j:
    lt = time.strftime('%A %d %B')
    st = item['start']
    st = datetime.strptime(st, '%A %d %B')

    if st == lt :
        item['start'] = datetime.strptime(st,'%H:%M') 

我有这样的错误:

File "/home/--/--/--/app/route.py", line 35, in file.py

st = datetime.strptime(st, '%A %d %B')

File "/usr/lib/python2.7/_strptime.py", line 328, in _strptime

data_string[found.end():])

ValueError: unconverted data remains: 02:05

你有什么建议吗 ？

我正在使用python(在LinuxMint中使用虚拟环境),我安装了pygal.

一切正常(渲染到html)但不渲染到svg或png.结果:只有黑色背景.

我安装cssselect并tinycss喜欢这里提到的.

它是第一次工作,但在重试时,我遇到了同样的问题.

(我不知道这是否相关,但在上周使用黑暗表格导出照片时,这种情况发生在我身上)

我使用pygal网站上的例子:

import pygal                                                       # First import pygal
bar_chart = pygal.Bar()                                            # Then create a bar graph object
bar_chart.add('Fibonacci', [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55])  # Add some values
bar_chart.render_to_file('bar_chart.svg')                          # Save the svg to a file

编辑:

bar_chart.render_to_png('bar_chart.png')

现在正在工作.

但不是:

bar_chart.render_to_file('bar_chart.svg')

是否有一个随时可用的引导程序包来添加其他颜色,而不是默认颜色？

默认颜色是(标签示例):

<span class="label">Default</span>
<span class="label label-success">Success</span>
<span class="label label-warning">Warning</span>
<span class="label label-important">Important</span>
<span class="label label-info">Info</span>
<span class="label label-inverse">Inverse</span>

我正在使用venv,我开发使用eclipse.我想添加一个联系页面.

我做了:

$ . bin/activate
$ pip install flask-wtf

我在forms.py中导入了一些模块:

我用过这个:

from flask.ext.wtf import Form, TextField, TextAreaField, SubmitField

然后这个:

from flask.ext.wtf import Form
from wtforms.fields import TextField, BooleanField

没有人工作,因为我有这个错误:

from flask.ext.wtf import Form
  File "/usr/local/lib/python2.7/dist-packages/flask/exthook.py", line 87, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.wtf

我正在使用python和schedule lib来创建一个类似cron的工作

class MyClass:

        def local(self, command):
                #return subprocess.call(command, shell=True)
                print "local"

        def sched_local(self, script_path, cron_definition):
                import schedule
                import time

                #job = self.local(script_path)

                schedule.every(1).minutes.do(self.local(script_path))

                while True:
                        schedule.run_pending()
                        time.sleep(1)

在主要时调用它

cg = MyClass()
cg.sched_local(script_path, cron_definition)

我懂了:

local
Traceback (most recent call last):
  File "MyClass.py", line 131, in <module>
    cg.sched_local(script_path, cron_definition)
  File "MyClass.py", line 71, in sched_local
    schedule.every(1).minutes.do(self.local(script_path))
  File "/usr/local/lib/python2.7/dist-packages/schedule/__init__.py", line 271, in do
    self.job_func = functools.partial(job_func, *args, **kwargs)
TypeError: the first argument must be callable

在类中调用另一个方法而不是sched_local时,比如

def job(self):
    print "I am …

我刚开始使用sqlite3和python.我想知道之间的区别:

cursor = db.execute("SELECT customer FROM table")
    for row in cursor:
              print row[0]

和

cursor = db.execute("SELECT customer FROM table")
    for row in cursor.fetchall():
              print row[0]

除了cursor是<type 'sqlite3.Cursor'>和cursor.fetchall()是<type 'list'>,它们都有相同的结果.

是否存在差异,偏好或特定情况,其中一个比另一个更优先？

当我运行这个bash脚本时:

if [ [$EUID -ne 0] ]; then
   echo "This script must be run as root" 1>&2 
   exit 1
else 

printf " whathever "

exit 0 
fi

我有这个错误:

./myScript: 15: [: Illegal number: [

你看到有什么问题吗？

我正在尝试使用以下方法创建 GKE 集群：

gcloud container clusters create mycluster --region europe-west1

但我有一个错误：

ERROR: (gcloud.container.clusters.create) ResponseError: code=403, message=Insufficient regional quota to satisfy request: resource "IN_USE_ADDRESSES": request requires '9.0' and is short '1.0'. project has a quota of '8.0' with '8.0' available. View and manage quotas at https://console.cloud.google.com/iam-admin/quotas?usage=USED&project=myproject-xxxx.

好像是资源IN_USE_ADDRESSES的限制有问题。这很奇怪，因为该项目是新的，因此除了要创建的集群之外，我没有任何资源。我有第二个项目，我在其中部署了 postgres 数据库。而已。

当我访问配额页面时，我似乎没有超过任何限制。

您的帮助将不胜感激。
