如何解决AttributeError: ''tuple'' 对象没有属性 ''encode'' MYsql

所以这是给我错误的代码

mycursor.execute("CREATE TABLE IF NOT EXISTS",str(share_name),"(nickname VARCHAR(255),date VARCHAR(255),bill VARCHAR(255),quantity VARCHAR(255),rate VARCHAR(255),amount(255))")
insert = f"INSERT INTO","(nickname) VALUES (%s)"
val = str(share_nick)
mycursor.execute(insert,val)

p 这是错误

Exception in Tkinter callback

    stmt = operation.encode(self._connection.python_charset)
AttributeError: ''tuple'' object has no attribute ''encode''

第 36 行是这个 mycursor.execute(insert,val)

我刚刚给出了实际上是错误的代码，如果你们需要其余的代码，请告诉我我会上传链接

解决方法

首先你所有的 insert 变量都是元组你没有正确使用格式或 f 字符串

insert = f"INSERT INTO {share_name} (nickname) VALUES (%s)"
mycursor.execute(insert,val)

我正在添加完整的代码

share_name = ''tableName'' # your table name
cursor.execute(f"CREATE TABLE IF NOT EXISTS {share_name} (nickname VARCHAR(255),date VARCHAR(255),bill VARCHAR(255),quantity VARCHAR(255),rate VARCHAR(255),amount varchar(255))") #you don''t have varchar in amount column
insert = f"INSERT INTO {share_name} (nickname) VALUES (%s)" # 
cursor.execute(insert,(1,))
cnx.commit() #commit is necessary to perform real insert 
cnx.close()

(h, w) = image.shape[:2] AttributeError: 'tuple' 对象没有属性 'shape'

如何解决(h, w) = image.shape[:2] AttributeError: ''tuple'' 对象没有属性 ''shape''

我一直在尝试实现用于对象跟踪的 OpenCv CSRT 算法。下面是代码。

from imutils.video import VideoStream
from imutils.video import FPS
import argparse
import imutils
import time
import cv2
file1 = ''traffic.mp4''
tracker = cv2.TrackerCSRT_create()
initBB = None
vs = cv2.VideoCapture(file1)
fps = None
while True:
    frame = vs.read()
    
    if frame is None:
        break
    frame = imutils.resize(frame,width=500)
    (H,W) = frame.shape[:2]
    if initBB is not None:
        (success,Box) = tracker.update(frame)
        if success:
            (x,y,w,h) = [int(v) for v in Box]
            cv2.rectangle(frame,(x,y),(x + w,y + h),(0,255,0),2)
        
        fps.update()
        fps.stop()
        
        info = [
            ("Tracker","CSRT"),("Success","Yes" if success else "No"),("FPS","{:.2f}".format(fps.fps())),]
    
        for (i,(k,v)) in enumerate(info):
            text = "{}: {}".format(k,v)
            cv2.putText(frame,text,(10,H - ((i * 20) + 20)),cv2.FONT_HERShey_SIMPLEX,0.6,255),2)
    cv2.imshow("Frame",frame)
    key = cv2.waitKey(1) & 0xFF
    
    if key == ord("s"):
        initBB = cv2.selectROI("Frame",frame,fromCenter=False,showCrosshair=True)
        tracker.init(frame,initBB)
        fps = FPS().start()
    
    elif key == ord("q"):
        break
        
vs.release()
cv2.destroyAllWindows()

我从 https://www.pyimagesearch.com/ 获得了代码。但是除了从命令行运行之外，他们还实现了网络摄像头和视频捕获选项的代码。但我只是想在我的 IDLE 中运行视频捕获选项。所以我修改了一些以在 IDLE 中运行。但是当我运行它时，我收到以下错误

line 20,in <module> frame = imutils.resize(frame,width=500)
  File "C:\\python37\\lib\\site-packages\\imutils\\convenience.py",line 69,in resize
    (h,w) = image.shape[:2]
AttributeError: ''tuple'' object has no attribute ''shape''

能否请您指出正确的方向。

解决方法

函数 .read() 返回一个布尔值 (True/False) 和一个框架（数组）。如果该帧被正确读取，它将是 True。因此，您应该将 frame = vs.read() 更改为 _,frame = vs.read()，如下所示（如果没有其他错误，我希望它可以正常工作）：

...
while True:
    _,frame = vs.read()
      
    frame = imutils.resize(frame,width=500)
    (H,W) = frame.shape[:2]
    ...

AsyncElasticsearch 客户端不接受与 AWS Elasticsearch 的连接 - AttributeError: 'AWS4Auth' 对象没有属性 'encode'

如何解决AsyncElasticsearch 客户端不接受与 AWS Elasticsearch 的连接 - AttributeError: ''AWS4Auth'' 对象没有属性 ''encode''

我在我的项目中使用 AWS Elasticsearch 和 async elasticsearch-py 包来连接集群。

AWS Elasticsearch 版本 7.9

Python 包：elasticsearch[async]==7.12.0

我无法使用 AWS4Auth 库（在官方 AWS ES 客户端 Python 文档中提到）初始化异步 Elasticsearch 客户端

它应该成功连接到客户端。但是，它给了我这个错误：

AttributeError: ''AWS4Auth'' object has no attribute ''encode''

分享我的代码片段：

from elasticsearch import AsyncElasticsearch,AIOhttpconnection
from requests_aws4auth import AWS4Auth
import asyncio
host = ''my-test-domain.us-east-1.es.amazonaws.com''
region = ''us-east-1''
service = ''es''
credentials = {
    ''access_key'': "MY_ACCESS_KEY",''secret_key'': "MY_SECRET_KEY"
}
awsauth = AWS4Auth(credentials[''access_key''],credentials[''secret_key''],region,service)
es = AsyncElasticsearch(
    hosts=[{''host'': host,''port'': 443}],http_auth=awsauth,use_ssl=True,verify_certs=True,connection_class=AIOhttpconnection
)
async def test():
    print(await es.info())
asyncio.run(test())

解决方法

我认为使用 AWS4Auth，您将绑定到 RequestsHttpConnection。

默认的连接类是基于urllib3的，比较多比可选的基于请求的类性能和轻量级。如果您需要任何请求，请仅使用 RequestsHttpConnection 高级功能，如自定义身份验证插件等。

来自https://elasticsearch-py.readthedocs.io/en/master/transports.html

试试：

es = AsyncElasticsearch(
     hosts=[{''host'': host,''port'': 443}],http_auth=awsauth,use_ssl=True,verify_certs=True,connection_class=RequestsHttpConnection
)

或非异步版本，如果上面的代码不起作用：

es = Elasticsearch(
     hosts=[{''host'': host,connection_class=RequestsHttpConnection
)

小编典典

您将在这里返回元组：

elif retailer_pk:    return (request, ''page-retailer-single.html'', {        "products": products,        "sorting": filt["sorting"],        "filtering": filt["filtering"],        "retailer": retailer,    })

您是否忘了在render此处添加：

elif retailer_pk:    return render(request, ''page-retailer-single.html'', {        "products": products,        "sorting": filt["sorting"],        "filtering": filt["filtering"],        "retailer": retailer,    })

有人可以帮忙吗？提前致谢

解决方法

问题是您在 get_msg 函数中返回了一个异常，大致如下所示：

def get_msg(item_number):
  try:
    ...do some stuff...
  except Exception as e:
    return e

看起来您在代码中的某处触发了 AttributeError 异常，并且您返回的是该异常，而不是 Email 对象。

您几乎不希望有一个 except 语句来抑制所有类似的异常，因为它会隐藏您的代码中的错误（正如我们在这里看到的）。捕获特定异常通常是更好的做法，或者如果您的代码尽管出现异常仍会继续，则至少记录错误。

作为第一步，我建议删除整个 try/except 块并让您的代码在没有它的情况下工作。
