電腦上已經(jīng)安裝了cvxpy庫，但是導(dǎo)入的時候出現(xiàn)如下錯誤提示

import cvxpy

---------------------------------------------------------------------------

RuntimeError Traceback (most recent call last)

RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

---------------------------------------------------------------------------

ImportError Traceback (most recent call last)

D:\ProgramData\Anaconda3\lib\site-packages\cvxpy\cvxcore\python\__init__.py in <module>

1 # TODO(akshayka): This is a hack; the swig-auto-generated cvxcore.py

2 # tries to import cvxcore as `from . import _cvxcore`

----> 3 import _cvxcore

ImportError: numpy.core.multiarray failed to import

發(fā)現(xiàn)出現(xiàn)上面的錯誤提示后，更新numpy庫就可以了

(base) C:\Users\Administrator>pip install numpy --upgrade -i https://pypi.douban.com/simple --use-feature=2020-resolver

雖然安裝過程中會提醒我們升級完了numpy庫版本到1.20.2的時候就與tensorflow沖突了。 2.4.1 requires numpy~=1.19.2

但是沒有關(guān)系，如果你不用tensorflow是沒事的。

Uninstalling numpy-1.19.5:

Successfully uninstalled numpy-1.19.5

ERROR: After October 2020 you may experience errors when installing or updating

packages. This is because pip will change the way that it resolves dependency co

nflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the

new resolver before it becomes the default.

tensorflow 2.4.1 requires numpy~=1.19.2, but you'll have numpy 1.20.2 which is i

ncompatible.

Successfully installed numpy-1.20.2

然后再執(zhí)行import cvxpy庫就沒有錯誤提示了。
