NumPy 未在 Jenkins 管道中导入

Question

我正在尝试在 Windows 代理上通过 Jenkins（在 Linux 上）运行 Python 脚本。 我的代码在 Jenkins 服务器和代理机器上运行，但在运行 Jenkins 管道时失败，因为无法加载 numpy。 我检查了 mkl-service 是否已安装。

有什么想法吗？

我的詹金斯文件：

pipeline {
agent none
options {
    skipStagesAfterUnstable()
}
stages {
    stage('Build') {
    agent {
            docker {
                image 'python:2-alpine'
    }
    }
        steps {
            sh 'python -m py_compile test.py'
        }
    }
    stage('Deliver') {
        agent {label 'CI-W10-Box'}
        steps {
            bat 'conda env remove -y --name test'
            bat 'conda env create' // Build environment based on environment.yml
            bat 'conda activate test'
            bat 'c:\\Users\\Ross\\anaconda3\\envs\\test\\python -c "import numpy"'
        }
        post {
            success {
                sh 'ls dist/gh'
                archiveArtifacts 'dist/gh'
            }
            always {
                cleanWs()
            }
        }
    }
}

}

我使用了简单的命令python -c "import numpy"来隔离问题并且它没有加载。 错误信息是：

C:\Users\Ross\workspace\test>c:\Users\Ross\anaconda3\envs\test\python -c "import numpy" 
c:\Users\Ross\anaconda3\envs\test\lib\site-packages\numpy\__init__.py:138: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured.

    from numpy.core._multiarray_umath import (
ImportError: DLL load failed while importing _multiarray_umath: The specified module could not be found.

此外，当我尝试python -c "import mkl"时，我得到ImportError: DLL load failed while importing _mklinit: The specified module could not be found. . 我想知道是否有需要设置的 PATH 变量或类似的东西。

修复方法是添加环境变量CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1 ，如下所示：

stage('Deliver') {
            agent {label 'CI-W10-Box'}
            environment {
                CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1
            }
            steps {
                bat 'conda env remove -y --name test'
                bat 'conda env create' // Build environment based on environment.yml
                bat 'conda activate test'
                bat 'c:\\Users\\Ross\\anaconda3\\envs\\test\\Scripts\\pyinstaller --onefile gh-debug.spec'
                //bat 'c:\\Users\\Ross\\anaconda3\\envs\\test\\python -c "import mkl"'
            }
            post {
                success {
                    sh 'ls dist/gh'
                    archiveArtifacts 'dist/gh'
                }
                always {
                    cleanWs()
                }
            }
        }
