ValueError: numpy.ndarray size changed, may indicate binary incompatibility

I am trying to get numpy<1.19.0 and ConfigSpace==0.4.16 to work in a python==3.7 conda environment. The installed version of numpy is 1.18.5.

I am getting the following error:

I tried suggested solutions suggested in other similar questions such as trying other versions of numpy or removing all numpy installations and reinstalling numpy and ConfigSpace with pip options --no-cache-dir --no-binary, but the error persists.

Are there other potential solutions that I could try?

I got some additional insight into the issue by consulting this GitHub issue page. As it turns out, if the size from the PyObject is smaller than the size from the C header, an upgrade of the package referenced by the error (here numpy) is necessary to resolve the error, and vice versa.

I was able to resolve the issue by upgrading numpy to version 1.20.0, even though the requirement was numpy<1.19.0.

Sharing this in case it helps others: I was trying to get fairseq to work and ran into the same issue of ValueError with binary incompatibility as possible reason and Jake's suggestion of updating numpy to 1.20.0 helped solve the problem even through requirements specifically asked for numpy<1.19.0.

I ran into the same problem: ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject and this solution worked for me. Specifically, using Dockerfile to create an image, I install flair==0.8.0.post1, which requires numpy<1.19.0. But after installing flair==0.8.0.post1 I install numpy==1.20.0 and this has avoided the problem. This section of the Dockerfile is:

RUN pip install flair==0.8.0.post1
RUN pip install numpy==1.20.0

意思是numpy版本太旧更新就好，更新完了还不行，就推出notebook重新进。

还有就是安装numpy权限不够，加一个user

pip install --user numpy
