When I am using replit I can remove the little symbol that appears when I drag and drop in a csv file so my main.py can read it, otherwise I get invalid literal base 10 issue. I am trying to run this on local machine with sublime text and getting same error now as it is reading the file from the directory, so I assume it is adding this symbol in before reading.... I can click on the csv file in replit and edit, but cannot do this in sublime.
Can someone explain what this is for? HOw can I get it to read the basic comma delimited numbers in the file (It is a game tile map).
with open(f'level{level}_data.csv', newline= '') as csvfile:
reader = csv.reader(csvfile, delimiter=',')
Saved it is comma delimited csv instead of UTF-8 comma delimited csv. It then imports without the 'question mark in a diamon' symbol. I understand this is an unrecognised special character, but I have nothing apart from integers in my table. Maybe someone could clarify that?...
I would like to import a csv-file into neo4j. This file was created by myself using the Mac textedit.app. The options in my textedit.app are set in such a way that there is "no css".
When I try to import the file neo4j says:
At [URL] # position 16471 - there's a field starting with a quote and whereas it ends that quote there seems to be characters in that field after that ending quote. That isn't supported. This is what I read: 'stylesheet"='
The problem is, there is no such line in the file. What's wrong?
Finally I solved the issue: the URL was a dropbox-URL, and instead of ?dl=0 one must state the option ?raw=1
I tried converting my .csv file to .dat format and tried to load the file into Octave. It throws an error:
unable to find file filename
I also tried to load the file in .csv format using the syntax
x = csvread(filename)
and it throws the error:
'filename' undefined near line 1 column 13.
I also tried loading the file by opening it on the editor and I tried loading it and now it shows me
warning: load: 'filepath' found by searching load path
error: load: unable to determine file format of 'Salary_Data.dat'.
How can I load my data?
>> load Salary_Data.dat
error: load: unable to find file Salary_Data.dat
>> Salary_Data
error: 'Salary_Data' undefined near line 1 column 1
>> Salary_Data
error: 'Salary_Data' undefined near line 1 column 1
>> Salary_Data

>> x = csvread(Salary_Data)
error: 'Salary_Data' undefined near line 1 column 13
>> x = csvread(Salary_Data.csv)

Ok, you've stumbled through a whole pile of issues here.
It would help if you didn't give us error messages without the commands that produced them.
The first message means you were telling Octave to open something called filename and it couldn't find anything called filename. Did you define the variable filename? Your second command and the error message suggests you didn't.
Do you know what Octave's working directory is? Is it the same as where the file is located? From the response to your load commands, I'd guess not. The file is located at C:/Users/vaith/Desktop. Octave's working directory is probably somewhere else.
(Try the pwd command and see what it tells you. Use the file browser or the cd command to navigate to the same location as the file. help pwd and help cd commands would also provide useful information.)
The load command, used as a command (load file.txt) can take an input that is or isn't defined as a string. A function format (load('file.txt') or csvread('file.txt')) must be a string input, hence the quotes around file.txt. So all of your csvread input commands thought you were giving it variable names, not filenames.
Last, the fact that load couldn't read your data isn't overly surprising. Octave is trying to guess what kind of file it is and how to load it. I assume you tried help load to see what the different command options are? You can give it different options to help Octave figure it out. If it actually is a csv file though, and is all numbers not text, then csvread might still be your best option if you use it correctly. help csvread would be good information for you.
It looks from your data like you have a header line that is probably confusing the load command. For data that simply formatted, the csvread command can bring in the data. It will replace your header text with zeros.
So, first, navigate to the location of the file:
>> cd C:/Users/vaith/Desktop
then open the file:
>> mydata = csvread('Salary_Data.csv')
mydata =
0.00000 0.00000
1.10000 39343.00000
1.30000 46205.00000
1.50000 37731.00000
2.00000 43525.00000
...
If you plan to reuse the filename, you can assign it to a variable, then open the file:
>> myfile = 'Salary_Data.csv'
myfile = Salary_Data.csv
>> mydata = csvread(myfile)
mydata =
0.00000 0.00000
1.10000 39343.00000
1.30000 46205.00000
1.50000 37731.00000
2.00000 43525.00000
...
Notice how the filename is stored and used as a string with quotation marks, but the variable name is not. Also, csvread converted non-numeric header data to 'zeros'. The help for csvread and dlmread show you how to change it to something other than zero, or to skip a certain number of rows. If you want to preserve the text, you'll have to use some other input function.
Hej,
no matter what I try, I keep getting the error: file not recognised as 'CSV data files' file, reason: null, while loading a cvs file into Weka explorer. Any suggestions what could be wrong?
I have been trying "correct" this type of errors Wrong number of values, Read 1, expected 2 Token[EOL], line 17 and after it stops giving those, the null one appears.
The file in question: file link
Thank you in advance!
I've preprocessed the file with these shell commands.
# optional:
# The file uses "\r" characters (sometimes displayed as ^M) characters
# as line separator. Character "\n" is better.
# make it a unix-compliant csv file
# original file is saved into ~/Downloads/rezultati.csv.bak
perl -pi.bak -E "s/\r/\n/g" ~/Downloads/rezultati.csv
# end optional
# take first 240 lines, except the defective last line .
# I don't know what's wrong with it. maybe it's "No newline at end of file"
# I'll just omit that single line starting with ID 243.
head -240 ~/Downloads/rezultati.csv > ~/Downloads/rezultati-240.csv
resultati-240.csv can be loaded into weka.
I have a txt file with some csv paths, for instance the file Links.txt which contains
/home/someone/something/aplha1.csv
/home/someone/something/aplha2.csv
/home/someone/something/aplha3.csv
/home/someone/something/aplha4.csv
I would like to read the file line by line using Julia Lang and then for each line to read the csv file. I am using the below code
open("Links.txt") do f
for line in eachline(f)
rawnames = readcsv(line)
println("read line: ", line)
end
end
Unfortunately I am getting error
ERROR: opening file /home/someone/something/aplha1.csv
: No such file or directory
Any ideas?
thx!
The problem is line contains the end-of-line character at the end. Try changing it to
readcsv(chomp(line))
