MacOs 10.15.5版本下内核函数无法加载

[qizou97]

Describe the bug MacOs 10.15.5版本下通过pip安装geatpy 2.5.1会导致内核函数无法正常加载。

import geatpy as ea Traceback (most recent call last): File "", line 1, in File "/Users/s1zer/anaconda3/envs/ml/lib/python3.8/site-packages/geatpy/init.py", line 17, in from boundfix import boundfix ImportError: dlopen(/Users/s1zer/anaconda3/envs/ml/lib/python3.8/site-packages/geatpy/core/boundfix.cpython-38-darwin.so, 2): Library not loaded: /usr/local/opt/gcc/lib/gcc/9/libgomp.1.dylib Referenced from: /Users/s1zer/anaconda3/envs/ml/lib/python3.8/site-packages/geatpy/core/boundfix.cpython-38-darwin.so Reason: image not found

@sizer74 我这边的mac10.14 python3.8测试正常。您的报错信息里面写到image not found似乎不是工具箱内抛出的异常。您试一下联系工作人员QQ1061655504看看能否远程协助解决，他已复工～

我这里遇到同样的问题，mac版本：10.14.2 安装方式 pip install geatpy。 应该不是个例，麻烦看下，多谢&辛苦啦

import geatpy as ea Traceback (most recent call last): File "", line 1, in File "/opt/anaconda3/envs/py3.7/lib/python3.7/site-packages/geatpy/init.py", line 17, in from boundfix import boundfix ImportError: dlopen(/opt/anaconda3/envs/py3.7/lib/python3.7/site-packages/geatpy/core/boundfix.cpython-37m-darwin.so, 2): Library not loaded: /usr/local/opt/gcc/lib/gcc/9/libgomp.1.dylib Referenced from: /opt/anaconda3/envs/py3.7/lib/python3.7/site-packages/geatpy/core/boundfix.cpython-37m-darwin.so Reason: image not found

@rubby33 @sizer74 经过夜以继日的研究，已经研究出解决办法。mac终端执行以下命令：

cd "$(brew --repo)"

git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile

source ~/.bash_profile

brew update

brew install libomp

至此就可以在mac上import geatpy了。

@1061655504

辛苦了，所以解决方法是安装 brew install libomp？

我以前安装过libomp9，现在我升级到libomp10 貌似问题依旧，见下面的日志：

@sizer74 你用这种方法解决了吗？

[geatpy-dev]

@sizer74 @rubby33 为了不给用户的安装和使用带来不便，下一个发行版将会彻底移除对openmp的依赖，届时直接安装就可以import了。给用户们带来不便我们在此深表歉意！

另外：当前版本（2.5.1），使用mac的用户可以用python3.5直接安装和使用，无需安装额外的依赖包。

python 3.7.7 geatpy 2.5.1 不能import，请问怎么办呢

[geatpy-dev]

@FaustDu hi，先用python3.5用着吧，部分苹果电脑的python3.6,3.7和3.8都出现了无法兼容的情况。

[joyc]

同样问题报备 macOS 10.15.6， py3.7.3。

[geatpy-dev]

已更新2.6.0，该问题已得到解决。
