ImportError: numpy.core.multiarray failed to import
: ImportError: numpi.core.multiarray failed to import 2, and imporplotlib fails to import 2. Now I want to talk about the real solution!!

: ImportError: numpy.core.multiarray failed to import
PIP install -u numpy
installation error

installation error

this error really took a long time, then reinstall matplotlib… The following
Ii. Reinstall Matplotlib
PIP install –upgrade matplotlib
It is much faster to use an image such as PIP install – I [mirror source link] -upgrade matplotlib
Summary of common mirror sources:

mirror tsinghua university open source station https://mirrors.tuna.tsinghua.edu.cn/ netease open source image https://opsx.alibaba.com/mirror/ http://mirrors.163.com/ alibaba open source image stand
Still report an error after that.

See a lot of blogs that mention python – M for installation
first type python-m PIP install-u PIP setuptools to upgrade, or directly jump to the next step
input python-m PIP install matplotlib for automatic installation, waiting for the completion of the installation.
