我正在使用烧瓶

在我的config.py中设置 UPLOAD_FOLDER = '/Users/kanel/Documents/Developments/upload'

和用于处理文件上传的控制器。

@app.route('/uploaded',methods = ['GET','POST'])
def upload_file():
   if request.method == 'POST':
      f = request.files['file']
      path = os.path.join(app.config['UPLOAD_FOLDER'],f.filename)
      print(path)
      model= Resnet50(weights='imagenet')
      img = image.load_img(path,target_size=(224,224))
      x = image.img_to_array(img)
      x = np.expand_dims(x,axis=0)
      x = preprocess_input(x)
      preds = model.predict(x)
      preds_decoded = decode_predictions(preds,top=3)[0] 
      print(decode_predictions(preds,top=3)[0])
      f.save(path)
      return render_template('uploaded.html',title='Success',predictions=preds_decoded,user_image=f.filename)

我收到此错误：

File "/opt/anaconda3/lib/python3.7/site-packages/PIL/Image.py",line 2766,in open
    fp = builtins.open(filename,"rb")
FileNotFoundError: [Errno 2] No such file or directory: '/Users/kanel/Documents/Developments/upload/chest-example.png'

我的路线出了什么问题？据说文件不存在，但是路径在那里！
