I am using node.js with reading file and writing another file with some modification.
I am facing problem. When i read the file, i got the below issue
détente - This word is converted to d�tente
I am using the following code.

The value is wrongly converted.

I'm trying to output an excel file from Talend 7.1. I've tried a few different setups and both xls and xlsx formats but they all result in the output file being corrupt and not being able to open it.
What am I doing wrong? I am loading an xlsx file into a database and this part works fine but outputting to excel I just can't figure it out! I was writing from the tMap directly to the tFileOutputExcel and it wasn't working (corrupt) so I changed it to write to a csv file first and then write that csv to the tFileOutputExcel but it is still corrupt.
This is my job detail:
And this is the settings in the tFileOutputExcel
I got this working by changing the transfer mode in the FTP component from 'ascii' to 'binary'. Such a simple thing but if this helps anyone else with this issue who is a newb like me :)
In connection with my earlier question, when I give the command,
filePath = sc.textFile("/user/cloudera/input/Hin*/datafile.txt")
filePath.collect()
some part of the data has '\xa0' prefixed to every word, and other part of the data doesn't have that special character. I am attaching 2 pictures, one with '\xa0', and another without '\xa0'. The content shown in 2 pictures belong to same file. Only some part of the data from same file is read that way by Spark. I have checked the original data file present in HDFS, and it was problem free.
I feel that it has something to do with encoding. I tried all methods like using replaceoption in flatMap like flatMap(lambda line: line.replace(u'\xa0', ' ').split(" ")), flatMap(lambda line: line.replace(u'\xa0', u' ').split(" ")), but none worked for me. This question might sound dump, but I am newbie in using Apache Spark, and I require some assistance to overcome this problem.
Can anyone please help me? Thanks in advance.
Check the encoding of your file. When you use sc.textFile, spark expects an UTF-8 encoded file.
One of the solution is to acquire your file with sc.binaryFiles and then apply the expected encoding.
sc.binaryFile create a key/value rdd where key is the path to file and value is the content as a byte.
If you need to keep only the text and apply an decoding function, :
filePath = sc.binaryFile("/user/cloudera/input/Hin*/datafile.txt")
filePath.map(lambda x :x[1].decode('utf-8')) #or another encoding depending on your file
I'm trying to load model files for a FisherFaceRecognizer. The initial problem is that the program was written for an older OpenCV version and it seems some interfaces were changed.
Info about my project:
programming language: Python 3.5
OpenCV Version: 3.3.0
These are the two lines were I had a problem with:
model = cv2.face.createFisherFaceRecognizer()
model.load('foo_model.xml')
In the OpenCV documentation I found out that there is a new way to call the create functions and it seems to work. But I could not find the right call for the load function. I have tried to use the read function of the recognizer, but that results in an error.
model = cv2.face.FisherFaceRecognizer_create()
model.read('foo_model.xml')
The error message I've got when I try to use read():
File can't be opened for reading! in function read
Does somebody can help me with loading the model files? Thank you :)
The problem is with the xml file format. if you open the XML file you will not find "my_object" tag. I will not go to the details of this but, every time I face this problem, it works when I modify the xml file as follows.
<?xml version="1.0"?>
<opencv_storage>
<my_object> //add this
.........
.........
.........
</my_object> //and this
</opencv_storage>
The problem seems to be that the xml format in which the models are saved had been changed. This seems to be a known issue. I am using OpenCV 3.3.0 and want to load a model from an older OpenCV version which results in the mentioned error from the read-function. In the OpenCV Q&A forum a solution was suggested to me, but in my case it did not work. Nonetheless I will drop the link to my post at OpenCV Q&A here. Maybe someone else with the same problem can benefit from it.
I'm trying to download an excel file which is uploaded on a Sharepoint 2013 site.
My code is as follows:
import requests
url='https://<sharepoint_site>/<document_name>.xlsx?Web=0'
author = HttpNtlmAuth('<username>','<passsword>')
response=requests.get(url,auth=author,verify=False)
print(response.status_code)
print(response.content)
This gives me a long output which is something like:
x00docProps/core.xmlPK\x01\x02-\x00\x14\x00\x06\x00\x08\x00\x00\x00!\x00\x7f\x8bC\xc3\xc1\x00\x00\x00"\x01\x00\x00\x13\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xb8\xb9\x01\x00customXml/item1.xmlPK\x05\x06\x00\x00\x00\x00\x1a\x00\x1a\x00\x12\x07\x00\x00\xd2\xba\x01\x00\x00\x00'
I did something like this before for another site and I got xml as output which was acceptable for me but I'm not sure how to handle this data.
Any ideas to process this to be like xlsx or xml?
Or maybe to download the xlsx another way?(I tried doing it through the wget library and the excel seems to get corrupted)
Any ideas would be really helpful.

Its too late but i got similar issue... thought it might help someone else.
try writing the output to a file or apply some encoding while printing.
writing to a file:
file=open("./temp.xls", 'wb')
file.write(response.content)
file.close()
or
file=open("./temp.xls", 'wb')
file.write(response.text)
file.close()
printing with encoding
print ( resp.text.encode("utf-8") )
or
print ( resp.content.encode("utf-8") )
!Make appropriate imports.
!try 'w' or 'wb' for file write.
Hope this helps.
It seems that the file is encrypted and request can't handle this.
Maybe the web service provides an API for downloading and secure decoding.
That's it:
I read successfully a DICOM file with itk::ImageFileReader.
Now I want to export an image.
I use vtkJPEGWriter.
When I add the line
vtkJPEGWriter* writer = vtkJPEGWriter::New();
even if that code doesn't run at the beginning of execution... I can't read the file. I comment the line, then I read the file again.
But the writer is not connected with the file reader. I don't get it. It has nothing to do at that moment!!
I'm wasting so much time, just trying to figure out what's the problem.
The problem is in the file. I don't know why it works with that file without that line. Really weird.
I just don't get it.
I will try with other files.
These lines are worked for me:
vtkSmartPointer<vtkJPEGWriter> JPEGWriter = vtkSmartPointer<vtkJPEGWriter>::New();
JPEGWriter->SetFileName("d:\\Tempx\\Pacienttest3\\Sagital.bmp");
JPEGWriter->SetInputConnection(m_pColor->GetOutputPort());
JPEGWriter->Write();
where m_pColor is kind of vtkImageMapToColors type ...
