ArrayFire tests fail at LAPack

[rwatkins77]

Trying to install arrayfire for CUDA on pop os 18.1. Tests of arrayfire fails at laPACK. Calculation of pi also fails at af.count() Any ideas? Have I left out dependencies? I followed the installation instructions and everything else is working. Output of arrayfire.tests attached.

@rwatkins77 The tests are not super reliable. Can you try using qr on a normal array to see if it works ?

[Pavan Yalamanchili]

@rwatkins77 can you show the error when you are calculating pi ?

[rwatkins77]

We were having problems with the cuda-toolkit and thought that we fixed them. Things (including the pi program) now work in command line python or ipython but not in spyder, where it doesn't detect the toolkit. This seems to be the source of the problem

[Matus Krajnak]

I have the same problem in ipython3 -m arrayfire.tests
Could be related to issue #183
af.count() fails for me in jupyter-notebook, not in ipython3

[Pavan Yalamanchili]

@matkraj Can we move the conversation to the other issue ?
