ValueError：numpy.ndarray 大小已更改，可能表示二进制不兼容

Question

我正在尝试让

numpy<1.19.0

和

ConfigSpace==0.4.16

在

python==3.7

conda 环境中工作。

numpy

的安装版本是

1.18.5

。

我收到以下错误：

我尝试了其他类似问题中建议的解决方案，例如尝试其他版本的

numpy

或删除所有

numpy

安装并重新安装

numpy

和

ConfigSpace

以及

pip

选项

--no-cache-dir --no-binary

，但错误仍然存在。

我可以尝试其他潜在的解决方案吗？

Answer 1

通过查阅此 GitHub 问题页面，我对这个问题有了一些额外的了解。事实证明，如果 PyObject 的大小小于 C 标头的大小，则需要升级错误引用的包（此处

numpy

）才能解决错误，反之亦然。

我能够通过将

numpy

升级到版本

1.20.0

来解决该问题，即使要求是

numpy<1.19.0

。

Answer 2

分享这个以防对其他人有帮助：我试图让 fairseq 工作，并遇到了同样的

ValueError

问题，可能的原因是二进制不兼容，而 Jake 的 suggestion 将 numpy 更新为

1.20.0

帮助解决了即使通过特别要求的要求也会出现问题

numpy<1.19.0

。

Answer 3

我遇到了同样的问题：

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

，这个解决方案对我有用。具体来说，使用 Dockerfile 创建镜像，我安装 flair==0.8.0.post1，这需要 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
