Question

我正在尝试与Docker一起运行我的应用程序的后端部分，该部分在尝试加载pickle文件时崩溃。我不明白为什么，因为只有Anaconda Jupyter Lab才能使一切正常运行。

我尝试使用以下命令在docker的anaconda中安装相同的熊猫版本： docker pull amancevice / pandas：0.24.2

这是有问题的代码

def encode(self,features):
        struct=joblib.load('/packages/marques.pkl')
        struct=struct.append(features,ignore_index=True)
        struct=pd.get_dummies(struct,columns=["MARQUE DATAFRIG "],dtype=float)
        restructured_features=struct.iloc[-1]
        restructured_features= pd.DataFrame(restructured_features).transpose()
        return restructured_features

DockerFile.back：

FROM continuumio/anaconda3:5.3.0

  RUN ln -fs /usr/share/zoneinfo/Europe/Paris /etc/localtime

  RUN dpkg-reconfigure -f noninteractive tzdata



EXPOSE 5000

DockerCompose文件：

以下是我运行代码后控制台中的部分内容：

Docker：ModuleNotFoundError：没有名为“ pandas.core.internals.managers”的模块； 'pandas.core.internals'不是一个包
