嗨伙计们,我在绘制条形图时遇到此错误,我无法摆脱它,我已经尝试了qplot和ggplot,但仍然是同样的错误.

以下是我的代码

 library(dplyr)
 library(ggplot2)

 #Investigate data further to build a machine learning model
 data_country = data %>%
           group_by(country) %>%
           summarise(conversion_rate = mean(converted))
  #Ist method
  qplot(country, conversion_rate, data = data_country,geom = "bar", stat ="identity", fill =   country)
  #2nd method
  ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_bar()

错误:

  stat_count() must not be used with a y aesthetic

data_country中的数据

    country conversion_rate
    <fctr>           <dbl>
  1   China     0.001331558
  2 Germany     0.062428188
  3      UK     0.052612025
  4      US     0.037800687

错误来自条形图而不是虚线图表.任何建议都会有很大帮助

嗨伙计们收到这个错误:

 'Index' object has no attribute 'labels'

回溯看起来像这样:

Traceback (most recent call last):

 File "<ipython-input-23-e0f428cee427>", line 1, in <module>
df_top_f = k.groupby(['features'])['features'].count().unstack('features')

 File "C:\Anaconda3\lib\site-packages\pandas\core\series.py", line 2061, in unstack
return unstack(self, level, fill_value)

File "C:\Anaconda3\lib\site-packages\pandas\core\reshape.py", line 405, in unstack
fill_value=fill_value)

File "C:\Anaconda3\lib\site-packages\pandas\core\reshape.py", line 90, in __init__
self.lift = 1 if -1 in self.index.labels[self.level] else 0

AttributeError: 'Index' object has no attribute 'labels'

在运行以下代码时

df_top_f = df.groupby(['features'])['features'].count().unstack('features')

df具有以下结构:

                                      features
             Ind                              
             0                         Doorman
             1                    Cats Allowed
             2                         Doorman
             3                    Cats Allowed
             4                    Dogs …

我正在研究postgres查询以从表中删除重复项.下表是动态生成的,我想编写一个select查询,如果第一行有重复值,它将删除记录.

该表看起来像这样

Ist col  2nd col
 4        62
 6        34
 5        26
 5        12

我想写一个select查询,删除第3行或第4行.

我正在使用 python 的 xlsxwriter 包来格式化我通过 mysql 查询生成的 Excel 报告。

问题是 sql 生成的报告动态返回列，因此他们无法事先知道将返回多少列。我试图仅将边框设置为返回的列数。但到目前为止，我只能对列数（A：DC）进行硬编码。任何人都可以帮我解决这个问题，我正在使用以下查询-

worksheet = writer.sheets['Sheet1']
formater = workbook.add_format({'border':1})
worksheet.set_column('A:DC',15,formater)
writer.save()

我第一次使用线程库是为了加快我的 SARIMAX 模型的训练时间。但代码不断失败并出现以下错误

Bad direction in the line search; refresh the lbfgs memory and restart the iteration.
This problem is unconstrained.
This problem is unconstrained.
This problem is unconstrained.

以下是我的代码：

import numpy as np
import pandas as pd
from statsmodels.tsa.arima_model import ARIMA
import statsmodels.tsa.api as smt
from threading import Thread

def process_id(ndata):
   train = ndata[0:-7]
   test = ndata[len(train):]
   try:
       model = smt.SARIMAX(train.asfreq(freq='1d'), exog=None, order=(0, 1, 1), seasonal_order=(0, 1, 1, 7)).fit()
       pred = model.get_forecast(len(test))
       fcst = pred.predicted_mean
       fcst.index = test.index
       mapelist …

当我试图运行下面的代码时,我最初收到以下错误 -

Error:-the JSON object must be str, not 'bytes' 

import urllib.request
import json
search = '230 boulder lane cottonwood az'
search = search.replace(' ','%20')
places_api_key = 'AIzaSyDou2Q9Doq2q2RWJWncglCIt0kwZ0jcR5c'
url = 'https://maps.googleapis.com/maps/api/place/textsearch/json?query='+search+'&key='+places_api_key
json_obj = urllib.request.urlopen(url)
data = json.load(json_obj)
for item in  data ['results']:
     print(item['formatted_address'])
     print(item['types'])

进行一些故障排除后的更改,如: -

 json_obj = urllib.request.urlopen(url)
 obj = json.load(json_obj)
 data = json_obj .readall().decode('utf-8')

 Error - 'HTTPResponse' object has no attribute 'decode'

我收到上面的错误,我已经尝试了stackoverflow上的多个帖子似乎没什么用.我上传了整个工​​作代码,如果有人能让它工作,我将非常感激.我不明白的是,为什么同样的事情对别人而不是我有用.谢谢!
