I don't think it's new:

>>> import numpy as z
>>> z.float128(3)
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    z.float128(3)
AttributeError: module 'numpy' has no attribute 'float128'
>>>

yet was it happening also in previous version ? It's not clear why/where "float128" is asked, and so where is the error.

numpy.float128 isn't supported on Windows using the MS compiler, which is used for NumpyMKL by WinPython. See https://stackoverflow.com/questions/9062562/what-is-the-internal-precision-of-numpy-float128

The problem is caused by either the pyqtgraph or the OpenGL package. Submitting an issue to the appropriate project would solve the problem. One answer on stackoverflow above is to change the reference to numpy.longdouble

@hirschbeutel create an issue on PyOpengl or PyQtgraph or StackOverflow, as it's not resolvable from WinPython.

It's a bug in PyOpenGL. I removed the offending lines and rebuilt ... https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopengl

Sorry, something went wrong.

it seems https://github.com/mcfletch/pyopengl is less maintained than https://github.com/cprogrammer1994 , but both are sort of mono-maintainer packages.

Sorry, something went wrong.
