AttributeErrors我在@property与 python 结合使用时遇到了一个问题__getattr__()：

示例代码：

>>> def deeply_nested_factory_fn():
...     a = 2
...     return a.invalid_attr
...
>>> class Test(object):
...     def __getattr__(self, name):
...         if name == 'abc':
...             return 'abc'
...         raise AttributeError("'Test' object has no attribute '%s'" % name)
...     @property
...     def my_prop(self):
...         return deeply_nested_factory_fn()
...
>>> test = Test()
>>> test.my_prop
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in __getattr__
AttributeError: 'Test' object …

我正试图从中文网站上抓取一些javascript生成的内容.我正在使用Selenium(和Python),因为我无法直接删除javascript内容.

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.selenium import selenium 

import time
import urllib2
import httplib
import urllib
import re
import base64

browser = webdriver.Firefox() # Get local session of firefox
browser.get("http://www...") # Load page (redacted here, but any works)
browser.get_body_text() #Attempt to scrape body text

我收到以下错误:

'WebDriver' object has no attribute 'get_body_text'

事实上,我似乎无法在selenium.selenium类中调用任何命令.毫无疑问,我忽视了一些非常明显的事情.提前致谢.

运行以下功能时:

def conEnclosure():
    freebay = open("freebay", "w+")
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    password = getpass.getpass("Enter the password for infra: ")

    for host in open("full.json", "r"):
        print host
        ssh.connect("%s" % host, username="infra", password="%s" % password)
        stdin, stdout, stderr = ssh.exec_command("show server info all")

我收到以下错误:

    Traceback (most recent call last):
  File "./findbay_v2.py", line 53, in <module>
    conEnclosure()
  File "./findbay_v2.py", line 41, in conEnclosure

  File "build/bdist.macosx-10.9-intel/egg/paramiko/client.py", line 364, in exec_command

我正在尝试运行一个简单的代码,我在我的Canopy中安装了matplotlib和numpy的所有依赖项.我仍然得到错误.

    import cv2

    plt.imshow(x, cmap = 'gray', interpolation = 'bicubic')
    plt.xticks([]), plt.yticks([])  # to hide tick values on X and Y axis
    plt.show()

使用django。我有以下模型：

class Postagem(models.Model):
id = models.AutoField(primary_key=True, editable=False)
descricao = models.CharField(max_length=50)
area = models.ForeignKey('core.Area', null=True)
user = models.ForeignKey('User')
categoria = models.CharField(max_length=50, null=True)
post = models.FileField(upload_to='posts/', null=True)
thumbnail = models.FileField(upload_to='posts/', null=True)


def __str__(self):
    return self.descricao

以下形式：

class PostForm(forms.ModelForm):
categoria = forms.ChoiceField(choices=[("Video","Vídeo"),("Audio","Aúdio"),("Imagem","Imagem"),("Musica","Música")], required=True)
thumbnail = forms.FileField(required=False)

class Meta:
    model = Postagem
    fields = ['descricao', 'area', 'user', 'post']

视图：

def profileView(request):
context = getUserContext(request)

if request.method == 'POST':
    exception=None
    userDict = {}
    userDict["user"] = context["user"].id

        newPost = request.POST.copy()
        newPost.update(userDict)

我试图在 colab.research 页面中运行我的神经网络，但AttributeError: module 'tensorflow' has no attribute 'optimizers'在这一行我仍然遇到错误：

opt = tensorflow.optimizers.RMSprop(learning_rate=0.00001, decay=1e-6)

我从代码中导入的部分：

import tensorflow
from tensorflow.keras.preprocessing.image import ImageDataGenerator
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense, Dropout, Activation, Flatten
from tensorflow.keras.layers import Conv2D, MaxPooling2D
from keras import optimizers

我在为 python 使用 jira 库时遇到了这个问题。尽管为基本身份验证设置了适当的参数，但我得到以下信息：

异常被忽略：<绑定方法魔术。德尔文件“/home/keckj/.local/lib/python3.6/site-packages/magic.py”，线路129，中：在0x7f2a4e5ff128 <magic.Magic对象>>回溯（最近通话最后一个）的德尔 如果self.cookie 和 magic_close: AttributeError: 'Magic' 对象没有属性 'cookie'

这是一个快速片段：

from jira import JIRA

user = 'xxxx.xxxxx@xxxxxx.com'
apikey = 'xxxxxxxxxxxxxxxxxxxxx'
jira_server = 'https://xxxxxxxxxx.jira.com'
options = {'server': jira_server}

jira = JIRA(options, basic_auth=(user,apikey))

issue = jira.issue("KEY-123")
issue_summary = issue.fields.summary
issue_description = issue.fields.description
print('JIRA ISSUE SUMMARY: %s' %str(issue_summary))
print('JIRA ISSUE DESCRIPTION: %s' %str(issue_description))

我已经通过谷歌挖掘了几个方向，但一直很短：

• https://github.com/Linaro/jipdate/issues/30
• https://github.com/ahupp/python-magic/issues/47
• __del__ 上的 Python 属性错误
• https://github.com/ahupp/python-magic/pull/222

每当调用 API 端点{{url}}/api/users/login对用户进行身份验证时，我都想从 RDS 检索用户数据，但是，我目前在从 RDS 检索数据时遇到问题。

错误堆栈跟踪

这是错误的完整堆栈跟踪：

当前包版本

Flask==1.1.2
Flask-Cors==3.0.10

我解决问题的尝试

我试图解决问题但无济于事的一些事情是：

• 使用 pymysql 连接器代替 mysqlconnector
• 降级烧瓶棉花糖==0.11.0
• 降级棉花糖==3.6.1
• 降级棉花糖-sqlalchemy == 0.23.1
