readlines function returns an empty string array
显示 更早的评论
I have a file with the extension "dataset", that follows the template shown below. When I have the following code:
lines = readlines("myfile.dataset","EmptyLineRule","skip")
I get an output of:
lines =
0×1 empty string array
Any ideas?
Template for dataset:
<Database Name>
<Image X Axis/Width> <Image Y Axis/Height>
<Count>
+1 <Path to Image 1>
+1 <Path to Image 2...>

No, because you forgot to attach the actual file with the paperclip icon.
If you have any more questions, then attach "myfile.dataset" with the paperclip icon after you read this:

Hmm evrything seems to work? You can try to zip the original file and upload the zip.
% read in the text file provided by the OP
lines = readlines("https://nl.mathworks.com/matlabcentral/answers/uploaded_files/1190428/face_train.txt","EmptyLineRule","skip");
% write the text into a .database file
writelines(lines,"myfile.dataset")
% now try to read the .dataset file
lines = readlines("myfile.dataset","EmptyLineRule","skip")

My first idea concerns the relative path:
lines = readlines("myfile.dataset", "EmptyLineRule", "skip")
Is the current folder really what you expect it to be? Check this:
D = dir(fullfile(cd, "myfile.dataset"))
Is this file empty? If so, specify the correct path instead:
folder = "C:\Your\Folder";
file = fullfile(folder, "myfile.dataset");
lines = readlines(file, "EmptyLineRule", "skip")
