face_recognition python flask不处理通过的图像

Question

我制作了Flask API，我想将图像从Flutter应用传递到API POST端点。我成功传输了图像，但是当我想在[]中使用它时

  first_image = face_recognition.load_image_file(image_from_post_request or down below image1)
它只是给我错误！

[当我尝试将此功能与本地保存的图像一起使用时，它将起作用。例如：

  first_image = face_recognition.load_image_file('./img/mj.png')
我已经尝试过在本地保存该帖子图像，然后对其进行解析，但这是行不通的。我是一个初学者，因此将不胜感激。

谢谢

我的代码：

@app.route('/compare', methods=['POST'])
  def compare():
  image1 = request.files['face1']
  image2 = request.files['face2']

  first_image = face_recognition.load_image_file(image1)
  first_image_encoding = face_recognition.face_encodings(first_image)[0]


  unknown_image = face_recognition.load_image_file(image2)
  second_image_encoding = face_recognition.face_encodings(unknown_image)[0]

  results = face_recognition.compare_faces([first_image_encoding], second_image_encoding)

  if results[0]:
      print('These images are same')
      return jsonify({'response' : 'These images are same'})
  else: 
      print('These images are not same')
      return jsonify({'response' : 'These images are not same'})
错误：
