Re: [Moses-support] Error in Train Phrase Model

[Tom Hoar]

As Barry noted, your logs show the command prompt path is "/root" which 
means you're probably running as root. Several years ago, we found are 
several ill-behaved utilities (in Moses and IRSTLM) that relied on 
access privileges to prevent deleting system files. Running as root 
bypassed this safety mechanism. Some were fixed, but others could remain.

Running Linux as root is generally a sign that the user is trying to 
make Linux more "Windows-like." You said, "i have only this user in the 
system." If you're referring to the "root" user, I don't know of any 
Linux distro that defaults to only one user with root privileges, but if 
this is true, I suggest you also change to a different Linux distro.

Learning how to properly work on a Linux system is your best safety 
mechanism. Per Hieu, rebuilding your OS from scratch is the only way to 
make sure you have everything you need.

You must re-install your operating system.

you may have deleted /dev/stdin by accident, or a script has deleted 
it. It is highly recommended not to use the root user, running as an 
ordinary user will prevent this.

Hi Mohammed

Sorry, I meant "ls -l /dev/stdin"

I would suggest you log in and run train-model.perl as a user other than
root.
