尝试使用numpy==1.20.0，它在这里可以工作，尽管其他情况不同(alpine 3.12上的python3.8)。

在你安装任何包之后，确保你重新启动内核并且应该工作。通常包会自动升级，你所需要的只是快速重启。至少，这在我的情况下工作，当我试图安装和使用石榴时，我得到了同样的错误。

使用python虚拟环境并安装gensim:

pip install gensim==3.8.3

这是一个更详细的版本的[SO]: ValueError: numpy。Ndarray大小改变，可能表示二进制不兼容。预期从C头得到88，从PyObject得到80 (@FZeiser的回答)(很棒的回答)。

简而言之，这是一个ABI变化(在NumPy中)。 因此，在任何情况下，2个版本(包含或不包含更改)都不应该混合在一起。 错误消息(对某些用户具有误导性)来自PyxDamerauLevenshtein。

1. NumPy

[NumPy]: NumPy 1.20.0 Release Notes - np的大小。Ndarray和np。Void_改变状态:

The size of the PyArrayObject and PyVoidScalarObject structures have changed. The following header definition has been removed: #define NPY_SIZEOF_PYARRAYOBJECT (sizeof(PyArrayObject_fields)) since the size must not be considered a compile time constant: it will change for different runtime versions of NumPy. The most likely relevant use are potential subclasses written in C which will have to be recompiled and should be updated. Please see the documentation for PyArrayObject for more details and contact the NumPy developers if you are affected by this change. NumPy will attempt to give a graceful error but a program expecting a fixed structure size may have undefined behaviour and likely crash.

[GitHub]： numpy/numpy – （v1.19.5） numpy/numpy/core/include/numpy/ndarraytypes.h#726：

#define NPY_SIZEOF_PYARRAYOBJECT (sizeof(PyArrayObject_fields))

是最后一个具有它的，在从v1.20.0开始的后续版本(及其之前的rc)中，该行将被注释掉。 这里值得一提的是，在相同的版本之间，一个新成员被添加到PyArrayObject_fields结构(大约20行以上):

void *_buffer_info;  /* private buffer info, tagged to allow warning */

错误消息中的数字(80和88)开始有了一些意义。

(上面的)两个版本之间有一个界限:任何用一个版本构建，用另一个版本运行的场景都是不受支持的。这就像滥用任何其他库一样:使用(headers和.so (.lib) from)一个版本构建，而使用(. so (.dll) from)另一个版本运行——当这两个版本API / ABI不兼容时。

出现2例:

构建>=v1.20.0，运行<=v1.19.5:不支持 构建<=v1.19.5，运行>=v1.20.0:技术上也不支持，但由于在编译(预处理)时间没有更多的值计算([SO]: LNK2005错误在CLR Windows窗体(@CristiFati的答案))，它将工作

[GitHub]: numpy/numpy - ENH,API:在数组上存储导出的缓冲区信息(1)是引入更改的提交。

2. PyxDamerauLevenshtein

[GitHub]: lanl/pyxDamerauLevenshtein - pyxDamerauLevenshtein是一个依赖NumPy的扩展模块(C + Cython)。源代码(间接地)包含ndarraytypes.h。

浏览[PyPI]: pyxDamerauLevenshtein(至少是最新版本)，只有一个二进制:OSX pc064和一个Python版本(可能是包发布时的LTS)。因此，在所有其他平台上安装pip时，它都是从源代码构建的。

为简单起见，将使用v1.5.3(如问题中所示)。 作为旁注，虽然setup.py需要NumPy >=v1.16.1，但有一个requirements.txt文件包含v1.16.1作为依赖项(这有点误导-特别是在浅显地研究时)。

错误消息是在v1.5.1中添加的(专门针对这个NumPy ABI更改)，然后在v1.7.0中试图在构建时摆脱对NumPy的依赖时将其删除。我想这是因为经常遇到这种情况所产生的噩梦(其他包取决于特定的NumPy版本)。 删除提交:[GitHub]: lanl/pyxDamerauLevenshtein -第一次尝试远离NumPy。

3.例子

一旦理论被搞清楚了，重现这个问题就不难了。 步骤:

安装NumPy <=v1.19.5 安装PyxDamerauLevenshtein v1.5.3

我在Win上准备了我的“演示”，因为它恰好是我目前启动的操作系统。 还有一些额外的命令用于捕获过程中的状态(在几个点上)。还有一些(不重要的)输出将被剥离:

原因很明显(尽管隐藏在详细的输出中):在构建PyxDamerauLevenshtein时，PIP(默默地和临时地)下载(并用于构建)NumPy v1.21.6(在本例中)，忽略现有的安装版本。然后，在运行时使用v1.19.5，因此出现错误。

注意:该问题在最新的PyxDamerauLevenshtein版本(回答时为v1.7.1)中不再重现。

4. 一个转折

正如问题中所提到的，这些东西似乎适用于Python 3.6。

一开始我认为这部分的提交(#1)是罪魁祸首:

+     if (_buffer_info_free(fa->_buffer_info, (PyObject *)self) < 0) {
+         PyErr_WriteUnraisable(NULL);
+     }

[Python.3.7。PyErr_WriteUnraisable(PyObject *obj)的状态(v3.7，但不适用于v3.6):

调用此函数时必须设置异常。

从那里，在[GitHub]: python/cpython - (v3.7.0) cpython/ python/ errors.c#206中，PyErr_GivenExceptionMatches似乎比v3.6.15更严格，这就是为什么在传递NULL时没有引发异常的原因。

但我错了，事情其实简单得多:

因此，在Python 3.6上，不会遇到这种情况，因为最新(构建的)NumPy版本是v1.19.5。

5. 结论

我故意在这个(简化的)场景(MCVE)中运行，以证明一个观点。 普通用户在安装依赖于旧NumPy版本的包时通常会遇到这种情况。但是由于更新的包版本(带有更新的依赖版本)不断出现，因此随着时间的推移，遇到它的机会逐渐消失。

然而，如果有人遇到了这个问题，这里有一堆(通用的)指导方针来克服它:

在安装PyxDamerauLevenshtein之前安装(upgrade) NumPy >=v1.20.0(最好)(或者更好:不再使用旧版本) 安装PyxDamerauLevenshtein >=v1.7.0 指导PIP ([PyPA。PIP安装)不升级依赖项 “手动”构建PyxDamerauLevenshtein (python setup.py Build)，在这种情况下，我注意到使用了现有的NumPy版本(这是人们所期望的(并且没有使用PIP))

请注意，这可能也适用于其他包，并且可能涉及其他限制 总而言之 检查: 在安装所有必需的包之后(可能会将NumPy降级到<=v1.19.5) 不断地(如果包安装是一个连续的过程) NumPy版本(pythnon -m pip freeze)，如果是这样，升级它(python -m pip upgrade NumPy)

Numpy 1.22版本为我解决了这个问题。

对我有用的是:

pip uninstall numpy
conda install -y -c conda-forge numpy

虽然听起来很奇怪……我甚至不需要用Conda卸载它，这对我来说似乎很奇怪。我使用的是python 3.9
