I installed Vowpal Wabbit 7.3.0 on linux mint. I was able to use the vw command training model and getting predictions.
However, I am not able execute vw-varinfo command. I am not able to find this command in vw --help. How can I solve it?
vw-varinfo is located in the utl directory. You can add it to your $PATH.

This is my first time trying to download a dataset ('train.csv') from the API.
I am currently trying to install in ubuntu the API with the instruction sudo pip install kaggle-cli but it's not being possible.
Error: pip: order not found
Is there any other option?
I want to work then with GNU (awk, bash,....)
The information I found is not being enough to solve the problem.
Could someone let me know how to install it?
Thanks.
Hi, I'm creating a small bash script. I would like to make this script portable to any Linux system without having to install any additional packages to make it work.
The problem is that this script uses the wmctrl tool, which isn't present on many distributions, so the question is:
I can arrange the distribution of a version of wmctrl which can be run on any distribution without having to install anything. Create a version of wmctrl that has no external dependencies.
it's possible? and if so, how? Can anyone help me?
I'm trying to install MOSEK on my Mac to use in MATLAB, but I could not get how to run the following step:
Run the command:
python <MSKHOME>/mosek/8/tools/platform/osx64x86/bin/install.py
where <MSKHOME> is the directory where MOSEK was installed. This will set up the appropriate shared objects required when using MOSEK.
Where should I run this command on MATLAB or terminal or something else?
Another question what exactly <MSKHOME> should be?
I've been trying to run a program that uses graphics (which I've already posted about here). This post and other posts have led me to the conclusion that I need create a ~/.bashrc and put in it:
alias ocaml="/usr/local/Cellar/ocaml/4.03.0/bin/ocaml”
However, /usr/local/Cellar/ocaml/4.03.0/bin/ocaml is not a valid file in my system. B/c when I ran this in the terminal:
$ cd /usr/local/Cellar/ocaml/4.03.0/bin
-bash: cd: /usr/local/Cellar/ocaml/4.03.0/bin: No such file or directory
But changing the version to 4.04.0 works:
$ cd /usr/local/Cellar/ocaml/4.04.0/bin
But when I ask the terminal what ocaml I'm running:
$ which ocaml
/Users/Username/.opam/4.03.0/bin/ocaml
It says I'm running 4.03.0
And my error message when I try to run an ocaml program using graphics is :
Error: Cannot find file /Users/Username/.opam/4.03.0/lib/ocaml/graphics.cma
So it seems like my terminal is running 4.03.0 but I don't have OCaml 4.03.0 in /usr/local/Cellar/ocaml/4.03.0/bin and instead I have 4.04.0??
That to me seems very strange.
If anyone could please help me out that would be greatly appreciated! I have spent hours trying to figure out how to run graphics on my computer and I have no clue why the solutions posted in previous StackOverflow posts are not helping :(
i don't find it strange.
The alias command works only in your terminal, not for the entire system.
Probably you have "/Users/Username/.opam/4.03.0/bin/ocaml" in your PATH variable.
I suggest to do:
export PATH="/usr/local/Cellar/ocaml/4.04.0/bin:$PATH"
then:
which ocaml
and the path should be the 4.04 version
It looks like that you have multiple installations of OCaml on your machine. Some of them being installed via opam, and others either manually, or via system package management. I would suggest just to ignore the latter and focus on opam.
To use opam, you need to activate your switch. This can be done manually,
eval `opam config env`
(Note the use of backticks)
You can also put it in your profile, so that opam will be activated every time you logged in. You can even ask opam to do it for you:
opam config setup --user
Finally, if you want to run a program, out of your normal terminal environment, and do not want to depend on some pre-setup steps (i.e., on a client's machine), then you can use opam config exec:
opam config exec -- ocaml my-ocaml-script.ml
I'll love something like Microsoft Visual Studio's line-by-line debugging in bash, with current variables values and so.
Is there any tool or way to do it? set -x and set -v are nice but not perfect.
See bashdb.
If it's installed on your system, see man bashdb.
If it's not installed, see http://bashdb.sourceforge.net
Yes. Use "bashdb" from http://bashdb.sourceforge.net/
Latest version at time of writing
http://sourceforge.net/projects/bashdb/files/bashdb/4.2-0.8/
If you are on a Mac (like I was) then you might need to install the GNU version of Bash.
I did that using "MacPorts"
http://www.macports.org/
Once you have MacPorts...
port install bash
Then follow the instructions to
./configure (in bashdb unpacked directory)
make
sudo make install
Then add the folder where bashdb can be found in your PATH
