#2018-10-23 15:48:47 October Tuesday the 43 week, the 296 day SZ
报错
  File "/Users/apple/Documents/ST/python/Python_test.py", line 4
    Out[5]:
          ^
SyntaxError: invalid syntax

源码：

from collections import defaultdict
dic = defaultdict(list)
dic['first']=1
Out[5]:
defaultdict(list, {'first': 1})
解决方案：

百度后，发现了如下一段代码。发现其实他们很多代码都是这样，

In [4]: li=[1,1.0,True,'hello',1+4j,[1,2,"hello"]]

In [5]: li[0]

Out[5]: 1

In [6]: li[-1]

Out[6]: [1, 2, 'hello']

结论：
这种代码写法：In[4]是输入，Out[5]是代表输出
他们排版有问题，导致他们的代码无法直接运行。想要运行上述代码，只需要删除
Out[5]:
defaultdict(list, {'first': 1})

修改为：

from collections import defaultdict
dic = defaultdict(list)
dic['first']=1
dic['two'] = 2
print(dic)

运行得到：
defaultdict(, {'first': 1, 'two': 2})

#2018-10-23 13:35:16 October Tuesday the 43 week, the 296 day SZ
Python2和Python3的区别
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(x)?

源代码：
print x 
修改：
print(x)

#2018-10-23 13:33:48 October Tuesday the 43 week, the 296 day SZ
NameError: name 'collections' is not defined
源代码：

queue = collections.deque([(source.x, source.y)])
修改：
from collections import deque
queue = deque([(source.x, source.y)])



#2018-10-23 13:28:07 October Tuesday the 43 week, the 296 day SZ
ModuleNotFoundError: No module named 'Queue'
源代码：        
import Queue
q = Queue.Queue(maxsize = n * m)

修改：
from queue import Queue 

q = Queue(maxsize = n * m)


#2018-10-23 13:26:23 October Tuesday the 43 week, the 296 day SZ

NameError: name 'xrange' is not defined

AttributeError: module 'sys' has no attribute 'maxint'
源代码：
        record = [[sys.maxint for _ in xrange(m)] for i in xrange(n)]
修改：

        record = [[sys.maxsize for _ in range(m)] for i in xrange(n)]
 

看了官网文档后了解python3中没有maxint了，只有maxsize

import sys

i = sys.maxsize

print(i)

 

官网说明文档：https://docs.python.org/3.1/whatsnew/3.0.html#integers



#2018-10-16 09:48:26 October Tuesday the 42 week, the 289 day SZ
            m2 = right - (right - m1) / 2
报错 

TypeError: list indices must be integers or slices, not float
解决方案：
            m2 = right - (right - m1) // 2


#2018-09-20 18:39:47 September Thursday the 38 week, the 263 day SZ
代码：
from sklearn.decomposition import PCA
import numpy as np 
import matplotlib.pyplot as plt 
import scipy.io

data = scipy.io.loadmat('docia.mat') # docia.mat其实是128个640*640的矩阵的叠加，当只有一个通道的时候就是黑白图片，3个通道是RGB图片，128个通道就是128个图片的叠加

#X = data['embedmap'][:,:,127]  #X里面是640个二维数组，每个数组里面有640个元素。也就是一个640*640的矩阵啦。
reshaped_data = data['embedmap'].reshape((409600, 128))   #reshape（）是数组对象中的方法，用于改变数组的形状。
#print(X.shape)
#print(len(X))
#print(len(X[0]))
#Y = data['embedmap'][:,:]
pca = PCA(n_components=3) #n_components返回所保留的成分个数n。
pca.fit(reshaped_data)  #fit(X)，表示用数据X来训练PCA模型；fit()可以说是scikit-learn中通用的方法，每个需要训练的算法都会有fit()方法，它其实就是算法中的“训练”这一步骤。因为PCA是无监督学习算法，此处y自然等于None。
PCA(copy=True, n_components=3, whiten=True) #whiten=True使得每个特征具有相同的方差。copy=True表示在运行算法时，将原始训练数据复制一份


pcaData=pca.fit_transform(reshaped_data)  #用X来训练PCA模型，同时返回降维后的数据。
res_pcaData = pcaData.reshape((640,640,3))
print(res_pcaData.shape)
print(res_pcaData)
plt.imshow(res_pcaData)
问题： 
Clipping input data to the valid range for imshow with RGB data ([0..1] for floats or [0..255] for integers).
分析：
我想画图展示三维数组，但是发现三维数组里面的数据是从-9到5的浮点数。这个imshwo函数只能展示0-255的数据


#2018-09-20 12:33:56 September Thursday the 38 week, the 263 day SZ
ValueError: Expected 2D array, got 1D array instead:
array=[-1. -1. -2.  1.  1.  2.].
#2018-09-20 11:36:31 September Thursday the 38 week, the 263 day SZ
代码：
from sklearn.decomposition import PCA
from sklearn.decomposition import PCA, IncrementalPCA
import numpy as np 
import scipy.io

data = scipy.io.loadmat('docia.mat') # 

X = data['embedmap'][:,:,127]
Y = data['embedmap'][:,:]
pca = PCA(n_components=3)
pca.fit(X)
PCA(copy=True, n_components=3, whiten=True)
dim_3 = pca.explained_variance_ratio_
print(dim_3) 
docia_3 = np.append(Y, dim_3,axis = 0)

报错
ValueError: all the input arrays must have same number of dimensions
分析： 
我想把降维后的3维度和以前的数组合并起来。
解决方案： 
方法错了，路线错了，放弃这种合并数组的方法，问题就是数组不匹配



#2018-09-20 10:41:58 September Thursday the 38 week, the 263 day SZ
代码：给128维度降维
import numpy as np 
import scipy.io

data = scipy.io.loadmat('docia.mat') # 

X = data['embedmap'][:,:127]


pca = PCA(n_components=3)
pca.fit(X)
报错
ValueError: Found array with dim 3. Estimator expected <= 2.

分析：PCA只能给2维度数组降维，
解决方案：
X = data['embedmap'][:,:127]
修改为：X = data['embedmap'][:,:,127]
添加逗号才是表示取其中的第三维的全部特征

这行没有问题，可以生成一个二维码图片让扫描登陆，然后看到微信最顶部说已经登陆了网页版微信，其实，我自己并没有登陆。
并且在下面记录聊天记录，但是只能和一个特定的群聊天
搞定了，里面有个group2这个东西，这个东西说明了只和某个群聊天。
因为@bot.register(group_2)
这个代码很神奇，他怎么知道是让我的微信登陆网页版，而不是其他人的微信登陆网页版。因为代码里面并没有提到我的微信相关信息
#2018-01-28 19:30:39 January Sunday the 04 week, the 028 day SZ SSMR
今天再次运行此代码，直接让我在微信上登陆网页版，没有了二维码登陆，很是奇怪。
后来用控制栏运行了，发现在该文件的文件夹里会产生两个文件，一个就是需要登陆的二维码文件，另外一个是db.sqlite3
因为文件夹里的二维码文件一直没有删除，所有程序会自动认出这段代码是我的账号。以后就不用删除那个登陆二维码，这样手机直接点击登陆就行。
删除两个文件重新运行，重新生成登陆二维码，扫描后竟然报错

UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 21: illegal multibyte sequence
[Finished in 1.0s with exit code 1]

解决办法：删除了复制代码test.py里面的汉字，通过判断#标志，删除对应行就行。

在Python处理字符编码时出现如下错误：

UnicodeDecodeError: 'utf8' codec can't decode byte 0xb1 in position 0: invalid start byte

此种错误，有几种可能： 
（1）要处理的字符串本身不是gbk编码，但是你却以gbk编码去解码 
比如，字符串本身是utf-8的，但是你却用gbk去解码utf-8的字符串，所以结果不用说，则必然出错

则必然会出现这类的错误，说是，用gbk的方式去解码字符串，想要获得Unicode字符串，但是结果却解码出错了

解决办法：

如果你确定当前字符串，比如抓取网页通过charset=utf-8，已经确定html的字符串是utf-8的，

则可以直接去通过utf-8去解码。


具体业务场景如下：

我读入一个编码为GBK的文件，解析里面的汉字，使用utf-8编码进行正则匹配，出现上述问题

解决方法：

设置python编码为GBK
 #encoding=utf8
 import sys
 reload(sys)
 sys.setdefaultencoding('gbk') 


python xml处理中文时出现的错误，记录一下，以免忘记

 

"UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 0: ordinal not in range(128)"

解决办法，在该python文件的前面加上如下几句，问题得到解决。

import sys
default_encoding = 'utf-8'
if sys.getdefaultencoding() != default_encoding:
    reload(sys)
    sys.setdefaultencoding(default_encoding)

我把这个电力数据放进文档里面，并且重命名为missing_data.xls。
import pandas as pd
data = pd.read_excel("missing_data.xls", header=None) 
mm = data.sum()
print (u'计算用电量总数:')
print (mm)这个就出现问题了，百思不得其解，后来百度后，网友说内容有问题，看着用notpad可以打开，但是用Excel但不开，
我后来新建立一个空Excel，把数据放进去，修改整齐，重新运行代码就好了

把出故障的这行tree = ET.parse(file_in)添加了出错机制，如果出错，报错并且继续处理下面的文件
try:
    tree = ET.parse(file_in):

后来用控制栏运行了，发现在该文件的文件夹里会产生两个文件，一个就是需要登陆的二维码文件，另外一个是db.sqlite3
因为文件夹里的二维码文件一直没有删除，所有程序会自动认出这段代码是我的账号。以后就不用删除那个登陆二维码，这样手机直接点击登陆就行。

UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 21: illegal multibyte sequence
[Finished in 1.0s with exit code 1]

解决办法：删除了复制代码test.py里面的汉字，通过判断#标志，删除对应行就行。

在Python处理字符编码时出现如下错误：

UnicodeDecodeError: 'utf8' codec can't decode byte 0xb1 in position 0: invalid start byte

此种错误，有几种可能： 
（1）要处理的字符串本身不是gbk编码，但是你却以gbk编码去解码 
比如，字符串本身是utf-8的，但是你却用gbk去解码utf-8的字符串，所以结果不用说，则必然出错

则必然会出现这类的错误，说是，用gbk的方式去解码字符串，想要获得Unicode字符串，但是结果却解码出错了

解决办法：

如果你确定当前字符串，比如抓取网页通过charset=utf-8，已经确定html的字符串是utf-8的，

则可以直接去通过utf-8去解码。


具体业务场景如下：

我读入一个编码为GBK的文件，解析里面的汉字，使用utf-8编码进行正则匹配，出现上述问题

解决方法：

设置python编码为GBK
 #encoding=utf8
 import sys
 reload(sys)
 sys.setdefaultencoding('gbk') 


python xml处理中文时出现的错误，记录一下，以免忘记

 

"UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 0: ordinal not in range(128)"

解决办法，在该python文件的前面加上如下几句，问题得到解决。

import sys
default_encoding = 'utf-8'
if sys.getdefaultencoding() != default_encoding:
    reload(sys)
    sys.setdefaultencoding(default_encoding)
