As per the #jigar Shah comment you have to first initalize upload library before resize
$this->load->library('upload');
$config['upload_path'] = './uploads';
$config['allowed_types'] ='csv|xls|xlsx';
$config['max_size'] = 1024; //in KB
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;
$config['max_filename'] = 25;
$this->upload->initialize($config);
if (!$this->upload->do_upload('image_name')) {
//if file upload failed then catch the errors
$this->handle_error($this->upload->display_errors());
$is_file_error = TRUE;
} else {
//store the file info
$image_data = $this->upload->data();
$config['image_library'] = 'gd2';
$config['source_image'] = $image_data['full_path']; //get original image
$config['maintain_ratio'] = TRUE;
$config['width'] = 150;
$config['height'] = 100;
$this->load->library('image_lib', $config);
if (!$this->image_lib->resize()) {
$this->handle_error($this->image_lib->display_errors());
}
}
