--------------------------------------
Hello! This bug is caused by syntax error in example DML file```Hello! This bug
is caused by syntax error in example DML
file```systemml-master/scripts/nn/examples/mnist_lenet.dml```
You can get some hints from log "Non-existing named function argument 'pad' in
call to forward." That means there exists illegal function parameter. In
file```systemml-master/scripts/nn/examples/mnist_lenet.dml```you can find code
like this
```python[outp1, Houtp1, Woutp1] = max_pool2d::forward(outr1, F1, Houtc1,
Woutc1, Hf=2, Wf=2,strideh=2, stridew=2, pad=0, pad=0)```Considering DML syntax
being like python syntax, I infer that function parameter
```pythonpad=0```in that script is illegal. So I replace all 12 funciton
parameter
```pythonpad=0```with just ```0```in DML
script```systemml-master/scripts/nn/examples/mnist_lenet.dml```.
Then I rebuild the systemML. I run the same code
```scalaval clf = ml.nn.examples.Mnist_lenetval dummy =
clf.generate_dummy_data```from
"http://apache.github.io/systemml/spark-mlcontext-programming-guide"; and got
same result as the tutorials tells.(I run this tutorials in spark-shell without
Zeppelin)
Following is the result
```scalascala> val dummy = clf.generate_dummy_dataSystemML Statistics:Total
