我想用double替换字符串中的所有单引号,除了"not","ll","m"等出现之外.

input="the stackoverflow don\'t said, \'hey what\'"
output="the stackoverflow don\'t said, \"hey what\""

代码1:(@ /sf/users/64327161/)

def convert_regex(text): 
     return re.sub(r"(?<!\w)'(?!\w)|(?<!\w)'(?=\w)|(?<=\w)'(?!\w)", '"', text)

有3种情况:'不在前面,后面跟不是字母数字字符; 或者之前没有,但后面跟着一个字母数字字符; 或者之前是字母数字字符,而不是字母数字字符.

问题:这不适用于以撇号结尾的单词,即大多数占有性复数,并且它也不适用于以撇号开头的非正式缩写.

代码2:(@ /sf/users/66743771/)

def convert_text_func(s):
    c = "_" #placeholder character. Must NOT appear in the string.
    assert c not in s
    protected = {word: word.replace("'", c) for word in ["don't", "it'll", "I'm"]}
    for k,v in protected.iteritems():
        s = s.replace(k,v)
    s = s.replace("'", '"')
    for k,v in protected.iteritems():
        s = s.replace(v,k)
    return s

要指定的单词太多,如何指定人员等等.请帮忙.

编辑1: …

下面有一个数值稳定的方法来计算softmax函数吗？我在神经网络代码中获得的值变为Nans.

np.exp(x)/np.sum(np.exp(y))

我有一本字典

event_types={"as":0,"ah":0,"es":0,"eh":0,"os":0,"oh":0,"cs":0,"ch":0}

我怎么能代替a通过append,s通过see,h通过horse,e通过exp与之间的空间.

输出如下:

{"append see":0,"append horse":0,"exp horse":0....}

import dropbox
client = dropbox.client.DropboxClient('<token>')
f = open('/ssd-scratch/abhishekb/try/1.mat', 'rb')
response = client.put_file('/data/1.mat', f)

我想将一个大文件上传到dropbox.我该如何检查进度？[文件]

编辑:以上的某种情况下,上传者也是如此.我究竟做错了什么

import os,pdb,dropbox
size=1194304
client = dropbox.client.DropboxClient(token)
path='D:/bci_code/datasets/1.mat'

tot_size = os.path.getsize(path)
bigFile = open(path, 'rb')

uploader = client.get_chunked_uploader(bigFile, size)
print "uploading: ", tot_size
while uploader.offset < tot_size:
    try:
        upload = uploader.upload_chunked()
        print uploader.offset
    except rest.ErrorResponse, e:
        print("something went wrong")

编辑2:

size=1194304
tot_size = os.path.getsize(path)
bigFile = open(path, 'rb')

uploader = client.get_chunked_uploader(bigFile, tot_size)

如何在requirements.txt文件中包含它？对于Linux:

pip install http://download.pytorch.org/whl/cu75/torch-0.1.12.post2-cp27-none-linux_x86_64.whl 
pip install torchvision

对于MacOS:

pip install http://download.pytorch.org/whl/torch-0.1.12.post2-cp27-none-macosx_10_7_x86_64.whl 
pip install torchvision 

校准:

我在Matlab中使用这个视觉工具箱校准了相机.我使用棋盘图像来做到这一点.校准后,我得到cameraParams,其中包含:

Camera Extrinsics
RotationMatrices: [3x3x18 double]
TranslationVectors: [18x3 double]

和

 Camera Intrinsics
 IntrinsicMatrix: [3x3 double]
 FocalLength: [1.0446e+03 1.0428e+03]
 PrincipalPoint: [604.1474 359.7477]
 Skew: 3.5436

目的: 我使用这台相机记录了一些运动物体的轨迹.每个对象对应于帧中的单个点.现在,我想要投射点,以便我得到一个顶视图.

1. 请注意我希望转换的所有这些点都在同一个平面上.

   例如:[xcor_i,ycor_i]

   -101.7000  -77.4040
   -102.4200  -77.4040
   

   Run Code Online (Sandbox Code Playgroud)
2. 关键点:此平面垂直于用于校准的棋盘图像之一.对于那张图片(下图),我知道棋盘的起点高度(193.040厘米).投影点的平面与地面平行并垂直于该图像.

代码 (参考:https://stackoverflow.com/a/27260492/3646408并在下面以@Dima回答):

function generate_homographic_matrix()
%% Calibrate camera
% Define images to process
path=['.' filesep 'Images' filesep];
list_imgs=dir([path '*.jpg']);
list_imgs_path=strcat(path,{list_imgs.name});

% Detect checkerboards in images
[imagePoints, boardSize, imagesUsed] = detectCheckerboardPoints(list_imgs_path);
imageFileNames = list_imgs_path(imagesUsed);

% Generate world coordinates of the corners of the squares
squareSize = …

错误:每当我在图中添加图例时,它都会给我这个错误:我不明白为什么？它完美无缺ax.legend().

我正在使用Kubuntu 16.04和kde 5.6.4.我安装了anaconda python 3.5,其中包括ipython qtconsole.

要启动ipython qtconsole,我必须输入ipython qtconsole终端.无论如何我可以为它创建一个发射器吗？

我知道有一个包,但它没有链接到anaconda python 3.5,我不想要另一个单独的python 3.5.
