Troubles with numpy

[sylas]

There is a long time it is installed(successfully) at C:\python35\\lib\site-packages. And its version is: 1.14.4
Strange enough python cannot find it !

At last found that there is no trouble if I use "python" instead of "ptpython". Look at this:

λ python

>>> numpy.__file__
