Python 导入错误：dlopen（…）：找不到符号：\uu PyCodecInfo\u GetIncrementalDecoder

我是python的初学者。 当我尝试

python链接器/examples/mnist/train\u mnist.py

时，出现了错误。 我想执行chainer

我该如何解决这个错误呢？

伙计，我在Mac Os El Captain中尝试使用opencv时也得到了类似的日志。经过一段时间的尝试，我从自制软件和pip中卸载了numpy。看起来他们在哪里发生了冲突。在那之后，通过自制软件安装就可以了

brew uninstall numpy
pip uninstall numpy
brew install numpy

如果这还不能尝试从自制软件重新安装python，请确保您的xcode命令行工具具有：

xcode-select --install

希望有帮助。

也许有帮助。
