Fred,
I have exactly the same issue as Tecx. I mean I got exactly the same
message as Tecx got when testing theano.
I am using Theano 0.9.0b1, libgpuarray 0.6.0, and iMac (Retina 5k, 27-in,
Late 2015) with AMD Radeon R9 M390 2048 Mb.
I wrote the .theanorc:
[global]
device = opencl0:1
floatX = float32
I wrote device = opencl0:1 because in a terminal I checked the device by:
python -c "import pygpu; print(pygpu.init('opencl0:1').devname)"
and got:
AMD Radeon R9 M390 Compute Engine
'opencl0:0' returns CPU.
Please advise.
