In Tensorflow/ Keras when running the code from https://github.com/pierluigiferrari/ssd_keras, use the estimator: ssd300_evaluation. I received this error.
Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above.
This is very similar to the unsolved question: Google Colab Error : Failed to get convolution algorithm.This is probably because cuDNN failed to initialize
With the issue I'm running:
python: 3.6.4.
Tensorflow Version: 1.12.0.
Keras Version: 2.2.4.
CUDA: V10.0.
cuDNN: V7.4.1.5.
NVIDIA GeForce GTX 1080.
Also I ran:
import tensorflow as tf
with tf.device('/gpu:0'):
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
with tf.Session() as sess:
print (sess.run(c))
With no errors or issues.
