我已经切换到新机器并试图使用我的代码（在前一个代码上工作）。 我正在使用python / django / Theano / Keras以及以下版本（当然与前一台机器对齐......）：
在其中一个导入中，我收到以下错误： （请注意，在其他情况下，我得到了缺少gof的错误......但这可能是一个不同的问题）
上次导入失败行：
AttributeError: 'module' object has no attribute 'poll'
任何想法？ 谢谢！

AttributeError: 'module' object has no attribute 'poll' 答案 0 :(得分：0)
解决！ 这个问题是gunicorn版本。 gunicorn没有使用pip冻结列出 - 因此如果版本对齐，我没有。 无论如何 - 这条线解决了这个问题：
sudo pip install gunicorn==19.4.5
请注意，您可能会对.theano文件夹的权限有一些问题。 在这种情况下，只需使用：
sudo chown django:django <your django folder>
谢谢！
