出于某种原因，我无法在 Jupyter Docker 容器中运行 SAS 笔记本。我可以通过 saspy 在Python笔记本中运行 SAS 代码，但 SAS 内核不断向我抛出错误。

我使用图像 jupyter/pyspark-notebook:notebook-6.4.2 作为基础，并通过 IOM 连接到远程服务器。如果我运行 Python 笔记本，例如

import saspy
%reload_ext saspy.sas_magic
ss = saspy.SASsession(cfgname="xxx")

然后连接工作正常。有时它会超时，但这可能是服务器问题。

但是，如果我运行 SAS 笔记本，当我尝试提交代码块时，我会得到一个错误结果：

[<class 'TypeError'>, TypeError("Frame 0 ({'shell': [b'f8fd30a1-60bc-4f25-...) does not support the buffer interface."), <traceback object at 0x7fad01e41100>]

运行容器的终端窗口中还有一堆错误信息：

dockerfile 旨在在公司防火墙后面使用，因此包含一些机密条目，因此很难给出可重现的示例。但它的要点是：

FROM jupyter/pyspark-notebook:notebook-6.4.2

RUN mamba install -c conda-forge -y nodejs && \
    conda clean --all -f -y && \
    fix-permissions $CONDA_DIR && \
    fix-permissions /home/$NB_USER

RUN pip install jupyterlab_templates &&\
    jupyter labextension install jupyterlab_templates && \
    jupyter serverextension enable --py jupyterlab_templates

RUN pip install pytest sas_kernel

# Adding SAS config
ADD saspy/*.jar /opt/conda/lib/python3.9/site-packages/saspy/java/
ADD saspy/sascfg_personal.py /opt/conda/lib/python3.9/site-packages/saspy/

一些特定版本：

Python 3.9.6

jupyter core     : 4.7.1
jupyter-notebook : 6.4.2
qtconsole        : not installed
ipython          : 7.26.0
ipykernel        : 6.0.3
jupyter client   : 6.1.12
jupyter lab      : 3.1.4
nbconvert        : 6.1.0
ipywidgets       : 7.6.3
nbformat         : 5.1.3
traitlets        : 5.0.5

sas-kernel                2.4.11
saspy                     3.7.5

我怎样才能解决这个问题？
