----------------------------------------
Summary: conv2d_bias_add fails w/ NPE on lenet with random data
Key: SYSTEMML-1589
URL: https://issues.apache.org/jira/browse/SYSTEMML-1589
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Assignee: Niketan Pansare
The lenet dml script fails with a null pointer exception for random multi class
data, generated with
{code}
X_full = rand(rows=60000,cols=784);
y_full = round(rand(rows=nrow(X_full), cols=1, min=1, max=10));
{code}
The detailed stacktrace is as follows:
