JIT issues when using jupyter notebook

首先在回報的 Jupyter 與 IPython 環境中重現 af.gaussian_kernel(128,128,5,5)，然後透過 arrayfire/image.py 與 arrayfire/util.py 追蹤該故障，直到 src/backend/cuda/jit.cpp。完成的標準是：在回報的設定下，該呼叫能在 Jupyter 中正常運作，且 CUDA JIT 錯誤已被理解或獲得阻止。

Hi, after updating to the latest arrayfire jupyter notebook seems to have a problem with af.gaussian_kernel() function. Standard ipython works without a problem but in notebook the call ends up with:

RuntimeError                          Traceback (most recent call last)
<ipython-input-3-e9e47878ee5a> in <module>()
----> 1 lala = af.gaussian_kernel(128,128,5,5)

I tried complete reinstall of python, cleaned any personal settings in .local .bashrc .config and installed completely new anaconda. Still whatever I do I cant get it to run

NOTE: af.constant() function works without problem
