Initializing libiomp5.dylib, but found libomp.dylib already initialized

原因及解决办法

numpy版本、pytorch版本冲突导致

conda remove mkl

conda install numpy==1.21.5

重新安装pytorch选择最新的版本

重新安装transformers

pip install transformers

成功不报错了：

原始报错截图：

详细步骤：

https://github.com/pytorch/pytorch/issues/78490

我安装的步骤：
1、anaconda官网下载安装

2、conda创建环境，python=3.9.0版本

3、pytorch官网安装命令执行

4、pip 安装transformers

运行transformers例子报错：

(transformers001) zarddeMacBook-Pro:~ zard$ python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('we love you'))"
OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://www.intel.com/software/products/support/.
Abort trap: 6
(transformers001) zarddeMacBook-Pro:~ zard$ conda remove mkl
Collecting package metadata (repodata.json): done
Solving environment: done

解决步骤：
1、执行：conda remove mkl 命令

2、重新安装numpy指定版本号

3、通过conda图形化界面，安装pytorch最新版本

4、重新安装transformers

执行成功了，见截图

看了网上其他解决办法，试了没有效果，例如：这两个：
1、https://stackoverflow.com/questions/53014306/error-15-initializing-libiomp5-dylib-but-found-libiomp5-dylib-already-initial

conda install nomkl

2、https://www.cnblogs.com/chester-cs/p/13022264.html

conda install nomkl

3、https://github.com/pytorch/pytorch/issues/78490
