我尝试创建一个Docker容器来部署在AWS lambda上，但我不断收到错误：

"Unable to import module 'app': No module named '_tkinter'", "errorType": "Runtime.ImportModuleError", "stackTrace": []}

我创建的Docker文件如下：

FROM public.ecr.aws/lambda/python:3.8
RUN yum -y update
RUN yum -y install gcc
RUN yum install -y gcc-c++
RUN yum install -y git
RUN yum install -y which
COPY requirements.txt ./requirements.txt
RUN pip install -r requirements.txt \
    && pip install -e git+https://github.com/ganesh3/icevision.git@master#egg=icevision[inference] --upgrade -q
COPY model_dir ./model_dir
COPY /app/app.py   ./
CMD ["app.handler"]

requirements.txt如下：

--find-links  https://download.pytorch.org/whl/torch_stable.html
torch==1.10.0+cpu 
torchvision==0.11.1+cpu
--find-links  https://download.openmmlab.com/mmcv/dist/cpu/torch1.10.0/index.html
mmcv-full==1.3.17
mmdet==2.17.0
numpy
Pillow
tk

The app.py is as below:

# app.py used in the early stages of the project just to test if I was able to import the icevision library
import sys
import os
print("Executing install for fonts")
os.system('mkdir -p /root/.icevision/fonts/')
os.system('curl -LJO https://raw.githubusercontent.com/airctic/storage/master/SpaceGrotesk-Medium.ttf')
os.system('cp SpaceGrotesk-Medium.ttf /root/.icevision/fonts/')
os.system('yum install -y tkinter tcl-devel tk-devel')
os.system('yum search tkinter')
os.system('yum install -y python3-tkinter.x86_64')
print("Before tkinter import")
import tkinter
print("After tkinter import")
import icevision
def handler(event, context): 
    return 'Hello from AWS Lambda using Python ' + sys.version + ' and IceVision ' + icevision.__version__ + '!'

我还使用以下命令登录到Docker容器：

docker exec -it <container_name> sh

然后我登录到python shell并运行：

>>> import icevision
Traceback (most recent call last):

    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'

我在Python壳里跑了下面：

import subprocess
subprocess.call(['pip', 'install', 'tk'])

我还运行了以下命令来安装tkinter：

yum install -y tkinter
yum install -y python3-tkinter

tkinter的导入仍然失败。我正在检查这个，因为我得到这个错误，无论是否导入tkinter，因为一些其他库正在内部导入它。
有人能建议修改以解决错误吗？
