The program doesn't reference any relative paths (paths starting with.The program uses cd (or equivalent) to change to an absolute path before doing any file operations (example: cd "$(dirname "$0")").The program doesn't perform any file operations itself (example: it only uses apt-get).These are possible circumstances where you wont need to use cd "$(dirname /path/to/file)" before running the program with any method: If at least one is true, you wont need cd first. When you don't need cd "$(dirname /path/to/file)" Returns: the predicted most likely class for the instance or Utils.missingValue () if no prediction is made. Parameters: instance - the instance to be classified. Note that a classifier MUST implement either this or distributionForInstance ().
usr/bin/env python3 /path/to/file # Use './file' if you wantįor Java executable jar's, you can simply use these commands (substituting /path/to/jar with the correct path): cd "$(dirname /path/to/jar)" # Not strictly necessary, see section below The instance has to belong to a dataset when it's being classified.
# Replace '/usr/bin/env python3' with the first line without the front #! Then run these commands in a terminal (substituting /path/to/file with the correct path) cd "$(dirname /path/to/file)" # Not strictly necessary, see section below If it says i386 only, then it's 32 bit.įor text based scripts (Bash, Python, Perl, etc.), you should use the command specified in the first #! line in the file.įor example, if the first line of the file is #!/usr/bin/env python3 Use this command to find out if a executable is 32 ( x86) or 64 ( x86-64) bit objdump -f "$file" | grep '^architecture' | cut -d, -f1 | sed 's/architecture: //' It can be corrected using command line arguments or Java modules. If the above doesn't work (or raises file not found errors), try using this before the above command cd "$(dirname /path/to/executable)"Īll the above commands will not work for text based scripts (Bash, Python, Perl, etc.), see below. A 'Runtime Components are Missing' error is generated by the Java Launcher. Use this command for executable files (substituting /path/to/executable with the correct path):Ħ4 bit executable files: /lib64/ld-linux-x86-64.so.2 /path/to/executableģ2 bit executable files: /lib/ld-linux.so.2 /path/to/executable
If it prints " You don't own the file", see "Change file ownership" below.Įxecute this command in a terminal sudo chown $USER:$(id -gn $USER) "/path/to/file"Īn answer I found from a comment by Lekensteyn on an answer for a question about chmod on NTFS partitions which I think deserves it's own question and answer, full credit to Lekensteyn. JAR. 2) Class path entries can contain the basename wildcard character, which is considered equivalent to specifying a list of all the files in the directory with the extension. Please take a look at Setting the CLASSPATH of Weka. If it doesn't see "Change file ownership" belowĮxecute this command in a terminal & echo "You don't own the file" 1) -jar option of java disables the use of CLASSPATH. Ensure that the 'Owner' field says your username.As an example, here on top of this slide, I have provided a path to this jar on.
Import do this before anything further (unless you are sure you own the file).Ĭheck and make sure that you own the file which you are trying to execute with one of the following methods. In this lesson, I will show you how to write stream in MapRreduce. It simply give you a taste of machine learning in Java.ĭownload stable.XX.zip, unzip the file, add weka.jar to your library path of Java project in Eclipse.Ĭreate a txt file "weather.txt" by following the following format: outlook This is a "Hello World" example of machine learning in Java.
