Question

我正在使用其他人的代码，可在GitHub上找到。为了运行他们的代码，我创建了一个virtualenv并安装了所有列出的依赖项 - python库和其他存储库的克隆。当我继续运行包含的测试时，我得到ImportError：

    Namespace(all=False, regr=False, sci=False, unit=True)
    [localhost] local: py.test -x -v engine/test

    Fatal error: local() encountered an error (return code 2) while executing 'py.test -x -v engine/test'

但是，如果我打开python解释器并尝试执行完全相同的导入，它就可以正常运行而不会出现任何错误。类似的问题建议：

将空__init__.py添加到测试目录
确保在virtualenv

pytest

我做了这两件事，错误仍然存在。

我添加到测试脚本的开头：

    import os
    print(os.environ["PYTHONPATH"].split(os.pathsep))
    print(os.listdir("."))

并确认我尝试导入的文件夹确实在结果列表中。

不确定如何继续。非常感谢我能得到的任何帮助：）

Answer 1

与其他图书馆存在冲突

编辑 - 这是我自己的愚蠢而不记得我已经克隆了以前版本的依赖回购，这也是我的路径，并且不包括此代码试图加载的功能。很抱歉，当我注意到没有删除问题时，我无法为我的生活找到删除按钮:)

Answer 2

在文件formula_img_validator.py中更改

from pyIMS.image_measures import measure_of_chaos,isotope_image_correlation, isotope_pattern_match

到

from engine.pyIMS.image_measures import measure_of_chaos, isotope_image_correlation, isotope_pattern_match

那将解决问题。要获得完整的解决方案go to GitHub for new updated code。

py.test：ImportError - 无法导入----
