In some cases, your system may display an error code indicating a weka error. There can be many reasons for this problem.
ArkansasIf customers are not familiar with Weka, the most common problem is that you cannot load your dataset into Weka because you either get an error like “Reason: java.io: IOException all files prematurely terminated, token [EOF ] read, line 1 ″, as well as “Arff file not recognized” or many other similar errors.

i to insert a large CSV file into Weka to support feature selection.the size of the csv file is undoubtedly 2.3 GB, it contains line 41 when using 2,000,002 columns.
and from the second line Swimmer Swimmer Swimmer ID … class (Y / N)
However, when I try to insert this information into weka, a pop-up error message appears:
How are error rates calculated in Weka classification?
It is calculated by separating a randomly expected chord from the observed chord and dividing it by the largest possible chord. A value better than 0 means that your classifier usually performs better than chance (it should!). Error rates are used for numerical prediction, not for classification.
weka.core.coverters.CSVLoader failed to load test.csv. Reason: lie numeric values. Read 1000002, originally granted 100001, read token string [EOL] Related to internet issue: 2
I need to open a computer csv file (saved by Openoffice Calc) in weka.
I always get the error: “Invalid numeric values: 140 read, 139 lines expected within 3”.
CSV has already been corrected with quotes in the shortcut area. And I counted 140 values available in the first lines.

How should I deal with error in Weka?
To avoid this error, open the control paper and select the columns one by one, then use Control + C to copy them into the final file you will be using. or you can use another method to avoid the commas at the end of each line. For a .CSV or .SEQ image, I got the same error. I solved it by converting it to help you to .arff first.

Just remove all double and single quotes from .csv, .xls file.
i.e. relatively, for example. If the value “john” is found under the name of the if line, a specific error is generated. Do this John by removing the quotes.
To remove all quotes, go to the FIND and Repair Excel file box.

I also faced the same issue when using Weka besides importing a CSV file.
The problem could be caused by incorrect formatting of the application
My file had a whole word in one of the GOV’T columns, I just deleted all “” and wrote the whole word GOVERNMENT and it worked.

I have the same error. The problem was the only reference character in the string value. The solution for me was to quote the entire string value.

This is due to the enhancement of the extra column. To remove this error, select the entire column and delete that column.This should be a good job. 🙂

I may have encountered this error. My CSV file offers a floating number of files. Solved the problem by replacing “” with “.

Why is Weka not loading a CSV file?
To get an idea of how things are> just get error messages. Weka uses its own backslash to avoid double quotes in production. In quotes inside cells (mostly used by LibreOffice, Excel, etc.). Tell me where you downloaded it. Loading … Thanks for your help! I have uploaded two arff files and they load fine.
