SyntaxError

[Chakazul]

SyntaxError occurs when calling reikna.cluda.any_api() in Windows 10 (PyOpenCL and Reikna installed). The same code has no problem in MacBookPro.

Traceback (most recent call last):
  File "Lenia.py", line 307, in compile_gpu

SyntaxError: invalid syntax

I see, async is a keyword starting from 3.7. I guess I'll have to change the API.

One of my user reported similar issue. Is the problem still exist, or should he update the driver / pycuda / pyopencl? https://github.com/Chakazul/Lenia/issues/13#issue-552866567

[fjarri]

This should be fixed starting from 0.7.3

Thanks fjarri! I will totally try 0.7.3 once it's out, and report back : ) Such an awesome project btw! (the cluda layer? genius!) thanks so much for making it public!

[fjarri]

No problem. 0.7.3 was released more than half a year ago :)

To be fair, the idea (and the name) of cluda was lifted from PyCuda/PyOpenCL. Incidentally, a big refactoring is underway, where cluda will be separated from high-level reikna stuff and will support multi-GPU setups transparently (among other things).

[danwills]

Ah yes, apologies I see it now. 0.7.3 (and 0.7.4) sort at the end of the tag list for me, maybe because they don't start with 'v'? Makes them quite easy to miss.

I'm up to date with origin/develop, so I would have thought that would include any fixes that were in 0.7.3, but I haven't checked.

The new refactoring effort sounds great! : )

[fjarri]

Ah yes, my bad about the tag names. The fix should indeed be in develop.
