I'm trying to install caffe on a Amazon Linux AMI. It has "yum" package manager. When I look at requirements, I see that, I have to run the following command:
sudo yum install gflags-devel glog-devel lmdb-devel
However, when I do this, I always get the following error:
No package gflags-devel available.
No package glog-devel available.
No package lmdb-devel available.
So, this command is from the official web page of caffe and therefore I believe there is no mistake in the installation command. My question is how can I fix the problem ? I'm a newbie on this issues and therefore sorry if my question is so simple.
Note : I know that there is a pre-installed caffe AMI available but I need to install it on my own instance.
EDIT
The only thing I could find is the that instance is Linux AMI 2016.03 Release.
EDIT2
I was able to install the aforamentioned packages by enabling other repositories as explained here and here.
As a final step I have to install opencv-devel package but guess what? Thanks to Amazon Linux AMI it does not exist too! So, if is there anyone who could tell me how could I solve this new problem, I'd be very appreciate.
You have to install opencv from source.
Linux AMI is based on cent OS. Here is a guide while wil help you to install opencv from source.

How can I install snap on my amazon linux 2?
I've gone through a few links on the web:
https://github.com/albuild/snap
https://forum.snapcraft.io/t/cannot-install-snapd-on-amazon-linux-2/20824/4
I can't seem to find correct instructions to install snap on my amazon linux 2 machine. I've done it before, but I forgot how I did it.

I am trying to install bigtop on centos6 (VM using virtualbox).
I am following links given below with little modifications to get latest versions (bigtop 1.1.0) -
http://www.dummies.com/how-to/content/set-up-the-hadoop-environment-with-apache-bigtop.html
https://cwiki.apache.org/confluence/display/BIGTOP/How+to+install+Hadoop+distribution+from+Bigtop+0.5.0
To be precise, I have run following commands till now -
wget -O /etc/yum.repos.d/bigtop.repo http://www.apache.org/dist/bigtop/bigtop-1.1.0/repos/centos6/bigtop.repo
yum install hadoop\* mahout\* oozie\* hbase\* hive\* hue\* pig\* zookeeper\*
Now the problem is, it says -
No package hadoop* available.
No package hue* available.
No package zookeeper* available.
I am new to linux and don't completely understand what exactly these commands are doing. I have wasted an entire day on this. As I am just trying to explore hadoop on my VM, I am fine if I can get some older version of bigtop too but I would prefer that I can get atleast hadoop 2.0 or above.
Can someone help on this?
Thanks.
You have to run sudo apt-get update between adding new repository and installing packages from it.
I have downloaded the Puppet Enterprise 3.7 installer from the PuppetLabs website,
but while installing I got the below error...
./puppet-enterprise-installer
ERROR: This is a supported platform, but this is not the installer for this platform. Please use the platform specific installer
(puppet-enterprise-3.7.2-el-6-x86_64).
How can I fix this?
You can get the enterprise linux puppet installer for 3.7.2 following this link.
https://s3.amazonaws.com/pe-builds/released/3.7.2/puppet-enterprise-3.7.2-el-6-x86_64.tar.gz
Looks to me like you downloaded it for the wrong linux distribution.
Hope this helps.
** This only applies to the open source version **
Which distribution are you installing this on? The error is telling you to use the EL6 install package which is available on their yum repo. It's much easier if you just install their repo package:
rpm -Uhv http://yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm
and then run yum install puppet facter.
A friend and I are interested in training the tesseract-OCR engine for a CV project. We tried using some wrappers such as PyTesser and pyocr, but the results are currently not as accurate as we need them to be. As such, we want to try training the tesseract to perform better for our purposes (i.e. identifying text on food labels), but are having some trouble installing the training tools.
What we've tried:
Looking on the google code website, the 'Compiling' page on the tesseract's google code wiki says the training tools are only available on version 3.03. However, the google code 'Downloads' page for tesseract-ocr only has the materials for 3.02. The bottom of the 'Compiling' page also has some comments about installing version 3.03 on Windows and OSX, but no comments yet for Linux users.
There also appears to be some sort of 3.03 source package for Ubuntu but we're not sure how to access it on our computers and the 'Compiling' page says we need to run these commands:
make training
sudo make training-install
We've also found a google group thread about tesseract 3.03 but again it seems like these posts do not include advice for Linux users (unless we missed something during the initial read).
Is this actually a really simple command-line install problem? Or, is there a way train tesseract with 3.02 (which we currently have installed)? Have we been looking at the wrong places for information?
Any advice or links to instructions for installing tesseract-ocr 3.03 for Linux distributions would be greatly appreciated! Thanks.
Tesseract can directly be installed in Ubuntu 14.04 using
sudo apt-get install tesseract-ocr
I don't have any idea if you can do it in older version of Ubuntu because the repo might be updated in later version of Ubuntu.
I had an aws ubuntu 14.04 instance.
when I tried installing Tesseract with
sudo apt-get install tesseract-ocr
It retuned package not found
But this worked for me.
sudo apt-get update
sudo apt-get install tesseract-ocr
Ubuntu is a debian based Linux distribution. The tesseract package you find will most likely be a debian package which will contain tesseract and the required default language files to allow you to run/train tesseract. You do NOT want the source package -- unless you just want to compile it yourself -- no need. You will not have to build tesseract, you just need to install the package. First, it appears you are new to Ubuntu, so please ready InstallingSoftware. It can be as easy as opening up an x-term and issuing the command apt-get install tesseract-pkgname (note: that means whatever the package name is).
There is no shortcut, take the time to understand whether you have a .deb package on your box that need to be installed or whether you are installing from a remote repository. The link above explains how to handle both.
Here is a specific Ubuntu thread dealing with installing tesseract Tesseract 3.0 + Ubuntu 10.04 Installation Guide Hope that helps. Tesseract is very good software.
I don't have any instructions for building Tesseract 3.03 for Linux specifically (I'm on Mac), but here's a link to download the source code for the 3.03 release candidate: https://tesseract-ocr.googlecode.com/archive/3.03-rc1.tar.gz
First run below command
sudo apt-get install tesseract-ocr
It will install tesseract version 3.04
Run below to update the tesseract
sudo apt-get --only-upgrade install tesseract-ocr
It will update tesseract to 4.1.3
I'm using CentOS 4.8 , i386.
I would appreciate if any one can help me to install Gnome (or any other GUI) while there is no yum available.
I tried to install yum but since It's a company's server with many things installed on it,
I faced with many problems.
However I decided to find a way to install Gnome without using yum
And please take note:
I'm a neophyte!
Did you try getting the source-code and building it manually?
You can get the code from
http://www.gnome.org/getting-gnome/
GNOME also provides a build tool to make the installation easier.
But, as it has already been pointed out - Servers are best managed over command line. It will give you more power and control over what you are doing.
