my controller:
public function show_info()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('Name', 'Name', 'required');

In your view file, you had wrote nmae except name
<div class="row">
<div class="form-group">
<div class="col-md-2"><label>Name</label></div>
<div class="col-md-10 col-md-pull-1">
<input name="Name" class="form-control" id="Name"
value="<?php echo set_value('Name')?>"
autocomplete="off"></input>
<?php echo form_error('Name'); ?>
</div>
</div>
