Valgrind provides you with the lines at which the error occurred at the end of each line in the format (file.c:line_no). Errors in valgrind are summarised in the following way: ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 0 from 0) The most common errors include: Illegal read/write er...

Sometimes we need to join multiple tables to get aggregate data in return. here is how we can achieve the same using CodeIgniter Query Builder / Active Records. public function getStudentInfo($studentid){ $query = $this->db->select("st.id, st.name, st.class, mk.maths, mk.science&quo...

To ensure that a GPU version TensorFlow process only runs on CPU: import os os.environ["CUDA_VISIBLE_DEVICES"]="-1" import tensorflow as tf For more information on the CUDA_VISIBLE_DEVICES, have a look to this answer or to the CUDA documentation.

import tensorflow as tf sess = tf.Session(config=tf.ConfigProto(device_count={'GPU': 0})) Bear in mind that this method prevents the TensorFlow Graph from using the GPU but TensorFlow still lock the GPU device as described in this an issue opened on this method. Using the CUDA_VISIBLE_DEVICES se...
