I have problems while reading file(utf-8) on release mode.
My code is like below.
Fixed code is as below.
However, I don't know why it is fixed..
I just switch wstring to string(char).
Could you explain why it is fixed?
The file which causes exception is over 1MB csv file.
My tbbmalloc_proxy.h is as below.
Thank you for reading.

I am using machine learning in my Python (version 3.8.5) code. In the preprocessing part, I need to hash encode few features. So earlier I have dumped a hash encoder pickle file using the features in the training phase. Saved the file with the name of 'hash_encoder.pkl'. Now in the testing phase, I need to transform the features using this pickle file. I'm using the following code given in screenshot to hash encode three string features as given in the first line.
In the encoder.transform line, I'm getting the error of "data_lock=mutiprocessing.Manager().Lock()".
At the end I'm also getting 'raise EOF error'.
I have tried using same version of pandas (1.1.3) to dump the hash_encoder file and also to load it. I'm not sure why is this coming up.
Can someone help me in understand or debugging this part?
I have added the screenshot of the error.

Any inputs...
Without the full trace it's hard to know exactly where this is failing. The method you pasted is just the p4yj wrapper method and we really would need to see the underlying Java Exception.
From what I can tell it looks like you are attempting to also use some options on the C* write that are unsupported. For example "MODE" - "DROPMALFORMED" is not a valid C* connector option. DataFrame Writer and Reader options are source specific so you are unfortunately unable to mix and match.
This makes me think that the data being written actually has a malformed date string or two and this code is dying when attempting to write the broken record. One way around this would be to attempt to do the date casting on CSV read which I believe does support DROPMALFORMED style parsing options.
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 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.
var filevalue=fs.readFileSync("file1.xml",'utf8').toString();
The value is wrongly converted.
Please assist me.
Note: I got answer the above issue: Thanks for reference

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 ...
