Error code 50 #148

Hello! I tried to run simple_example_HH.py in the examples folder, but have encountered an error. Below is the error message.

All the other scripts in the examples folder seem to work fine, so I am quite confused about this error. It seems to imply that something is wrong with NVCC. I am using brian2 version 2.5.0.3 and pip-installed the master branch of brian2genn. Thanks for your help!

See the output above (if any) for more details.

Hi @aiwenxu . This seems to be the same issue as #133 , which is unfortunately not yet fixed. The current workaround is to use floating point literals instead of integer literals in equations, e.g. instead of exp(-(V+60)/18) write exp(-(V+60.0)/18.0). I updated the simple_example_HH.py example in the repository to apply this workaround (https://github.com/brian-team/brian2genn/blob/master/examples/simple_example_HH.py ), it should work now hopefully.

It is working, thank you! I will go ahead and change my old code for it to work with the new version.

Actually, downgrading makes my life a lot easier lol :)
