I just installed toad-0.0.62 using pip and success

but when I import

import toad

the result

ValueError                                Traceback (most recent call last)

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

What I try is upgrade my numpy from 1.19.2 to 1.20.1 (requirement 1.18.0) but still same error, I'm using python 3.8.6

  • maybe the solution is to reinstall numpy. like he did here https://stackoverflow.com/questions/66060487/valueerror-numpy-ndarray-size-changed-may-indicate-binary-incompatibility-exp – shv Feb 19 '21 at 04:51

    Already upgrade from 1.19.2 to 1.20.1, actually the requirement is 1.18.0 – Nabih Bawazir Feb 19 '21 at 04:52
  • try removing it all together, and then try to install it from scratch. sometimes upgrading leave traces of the old version. – shv Feb 19 '21 at 04:57

I get the similar issue，when I install toad-0.0.65

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

pip install numpy==1.20.1 toad

And restart your current notebook for update cache，toad will work.
