ERROR: @cutensor not defined #78

Closed lihebi closed 4 years ago

lihebi commented 4 years ago

This is weird enough. I'm on master branch:

Pkg.status()
...
([6aa20fa7] TensorOperations v2.1.1 #master (https://github.com/Jutho/TensorOperations.jl.git)
...
using TensorOperations: @cutensor

fail with

ERROR: UndefVarError: @cutensor not defined
Jutho commented 4 years ago

Did you also load CuArrays?

lihebi commented 4 years ago

Yes, I did. I just tried a new session with only CuArrays and TensorOperations, same error. I had no problem running Flux models on GPU with CuArrays.

Jutho commented 4 years ago

Do you have CUTENSOR installed.

Jutho commented 4 years ago

You can check with CuArrays.has_cutensor()

lihebi commented 4 years ago

I don't. I assumed it was installed by default with CUDA. Let me try it.

lihebi commented 4 years ago

It works after installing cuTENSOR. Thanks!

Jutho commented 4 years ago

Great. In time, I hopte to have GPU implementations which do not depend on CUTENSOR as fallback, but for now this is a necessary requirement.

mdav2 commented 4 years ago

I'm getting this same error within a package of mine. I'm not sure what may be causing it, because I read this thread and installed cuTENSOR. In a REPL, I'm able to use @cutensor just fine, but when attempting to import the macro in a submodule I get,

Running println(CuArrays.has_cutensor()) right before using TensorOperations: @tensoropt @cutensor prints true.

lpawela commented 3 years ago

Is there any update on this. I seem to be facing the same issu as @mdav2 when developing my package. Testing the package crashes on precompilation, but before the crash I can confirm that CUDA.has_cutensor() = true. The next lines are
