初めまして。私は現在Python及びTensorFlowを用いて、個人の趣味で画像認識のWebアプリを開発している者なのですが、実際に以下のWeb実行用ファイル(記述はPython)を実行するとJinja2のエラーが発生してどうすればよいのかわかりません。  
なお、使用しているソフトウェアはPycharm(Community Edition
2018.1.4)で、実行も同様のソフトウェアを使用しています。OSはWindows10です。また、Anaconda3も使用しています。  
以下は元のプログラム（Web用）のコードです。

[code]

    # -*- coding: utf-8 -*-
    
    import tensorflow as tf
    import multiprocessing as mp
    from flask import Flask, render_template, request, redirect, url_for
    import numpy as np
    from werkzeug import secure_filename
    import os
    import eval
    
    # 自身の名称を app という名前でインスタンス化する
    app = Flask(__name__)
    app.config['DEBUG'] = True
    # 投稿画像の保存先
    UPLOAD_FOLDER = './static/images/default'
    
    # ルーティング。/にアクセス時
    @app.route('/')
    def index():
      return render_template('index.html')
    
    # 画像投稿時のアクション
    @app.route('/post', methods=['GET','POST'])
    def post():
      if request.method == 'POST':
        if not request.files['file'].filename == u'':
          # アップロードされたファイルを保存
          f = request.files['file']
          img_path = os.path.join(UPLOAD_FOLDER, secure_filename(f.filename))
          f.save(img_path)
          # eval.pyへアップロードされた画像を渡す
          result = eval.evaluation(img_path, './model2.ckpt')
        else:
          result = []
        return render_template('index.html', result=result)
      else:
        # エラーなどでリダイレクトしたい場合
        return redirect(url_for('index'))
    
    if __name__ == '__main__':
      app.debug = True
      app.run(host='0.0.0.0')
    
[/code]

エラー内容は以下の通りです。

基本的に[こちらのサイト](https://qiita.com/AkiyoshiOkano/items/dc19bffc88c549393699)(顔認識のWebアプリを開発している方)を参考(というかコードをほとんど引用)にしているので、Jinja2のことについてはよくわかりません。  
上記のエラーに対してどう対処すればいいのか教えていただければ幸いです。

question
python tensorflow windows-10 flask
Pythonファイルを実行した際の「jinja2.exceptions.TemplateSyntaxError: unexpected '>'」というエラー


エラーメッセージから判断すると、アプリケーションの`templates`ディレクトリにある'index.html'又はそれの親となっているhtmlファイルに記述ミスがあります。ミスの内容は、エラーメッセージのとおりで、予期しない（unexpected）
'>' です。
