Pandas: AttributeError: 模块“pandas.core.computation”没有属性“表达式”

如果您将 dask 版本更新为 >= 0.15.3，那么一切都应该很好。

我的 dask 是 0.15.3，我收到这个错误！！

这解决了这个问题
pip install dask --upgrade

完全忘记加载我正在使用的 Anaconda 模块。
尽管将 dask 升级到最新版本，但我仍然遇到此问题！

更新 dask 确实有帮助，我正在使用 tensorflow 1.10 并将 dask 升级到 1.9.0。 我在使用 tensorflow 时遇到了类似的问题。

这解决了这个问题
pip install dask --upgrade
