MNIST_simple.jl and MNIST_full.jl really slow.

Hello, I finally succeeded in installing the tensorflow.jl and passed Pkg.test("TensorFlow") in Ubuntu.

But when I run the MNIST examples, it runs really really slow. The 1000 iteration take at least one day....

Is this as expected or sth is wrong? I tried either with CPU and GPU (My Graphic card is not that powerful), but I do not see any difference between them.

I don't think that is normal. How long does PKG.test take?

The Pkg.test feels normal. The logistic example also ran through pretty fast. These two samples are however too slow.
