[theano-users] How to run a single failing test, and what might the error I have be about?

[Marcelo Siero]

I get this error on a new installation. It has a GPU, but I have not
modified my configuration.
It is on a CENTOS 7 machine, and I followed the bleeding edge instructions.
When I run:
THEANO_FLAGS=''; python -c "import theano; theano.test()"

After a long time, I got this error:
Traceback (most recent call last):
File
"/home/siero/.local/lib/python2.7/site-packages/theano/sandbox/cuda/tests/test_basic_ops.py",
line 1069, in test_adv_sub1_fast

File "mtrand.pyx", line 167, in mtrand.cont0_array
(numpy/random/mtrand/mtrand.c:6127)
TypeError: 'float' object cannot be interpreted as an index

It then said:
Ran 26010 tests in 15484.861s

But no summary as to how many other errors.
I would like to run this particular test only.

I have 2 GPU's and will be enabling them. But for now, I would like to run
just the one unit
test that is failing. I saw no instructions in the FAQs as to how to do
that.

Tests should be run with device=cpu. They enable the GPU individually when
needed.

Make sure to Theano theano 0.9, I think this type of errors got fixed
before that release.

I would also suggest to the Theanno new gpu back-end:

It's still happening. I installed Theano 0.9, ran the test for a while, and
got the following.

It looks like an issue in the test itself (maybe that only shows itself
with newer versions of numpy or something).
This can be safely ignored.

I confirm Pascal answer. The problem is that your NumPy version is more
recent then your Theano version. As Pascal told, you can ignore it or
update Theano to the dev version.
