我现在正在尝试构建我的docker镜像我有我的app.py：

import pandas as pd
from flask import Flask, request, render_template
import os
from joblib import load

MODEL_DIR = os.environ["MODEL_DIR"]
MODEL_FILE = os.environ["MODEL_FILE"]
METADATA_FILE = os.environ["METADATA_FILE"]
MODEL_PATH = os.path.join(MODEL_DIR, MODEL_FILE)
METADATA_PATH = os.path.join(MODEL_DIR, METADATA_FILE)

app = Flask(__name__)

#Loading model
clf = load(MODEL_PATH)

@app.route('/', methods=['GET', 'POST'])
def index():
    result = ''
    text = ''
    #print(clf.predict(["I am angry"]))
    if request.method == 'POST':
        text = request.form.get("textTocompute")
        result = clf.predict([text])
    return render_template("index.html", result=result, text=text)
    
if __name__ == "__main__":
    app.run(host='0.0.0.0')

和Dockerfile：

FROM python:3.6

WORKDIR /app

RUN mkdir ./mlsample

RUN mkdir ./mlsample/model

ENV MODEL_DIR=app/mlsample/model

ENV MODEL_FILE=clf.joblib

ENV METADATA_FILE=metadata.json

ENV FLASK_APP=app.py

COPY requirements.txt .

RUN pip install -r requirements.txt

COPY reviewDataCleaned.csv .

COPY docker-ml.py .

RUN python ./docker-ml.py

COPY app.py .

COPY templates ./templates

EXPOSE 5000

CMD ["python", "app.py"]

我想构建这个但是我收到此错误：
