我得到了valueError:输入包含NaN、infinity或对dtype（'float64'）太大的值。在Jetson Nan上跑步的时候

Question

当我使用knn进行识别并运行以下函数时：

def predict(X_img_path, knn_clf=None, model_path=None, distance_threshold=0.49):
   if not os.path.isfile(X_img_path) or os.path.splitext(X_img_path)[1][1:] not in 
   ALLOWED_EXTENSIONS:
       raise Exception("Invalid image path: {}".format(X_img_path))
   if knn_clf is None and model_path is None:
       raise Exception("Must supply knn classifier either thourgh knn_clf or model_path")
   if knn_clf is None:
       with open(model_path, 'rb') as f:
           knn_clf = pickle.load(f)

   X_img = face_recognition.load_image_file(X_img_path)
   X_face_locations = face_recognition.face_locations(X_img)

   if len(X_face_locations) == 0:
      return []
   faces_encodings = face_recognition.face_encodings(X_img, 
   known_face_locations=X_face_locations)
   closest_distances = knn_clf.kneighbors(faces_encodings, n_neighbors=4)   

我有个错误：

Traceback (most recent call last):
File "Recognition.py", line 225, in <module>
predictions = predict(full_file_path, model_path= 
"/home/abc/FS/trained_knn_model.clf")

  closest_distances = knn_clf.kneighbors(faces_encodings, n_neighbors=1)

当我在我的cpu上运行相同的代码时，它工作正常，但是当我在jetson nano上运行时，它显示了上面的错误

我的jetson nano配置是

喷气背包4.2.1 r32.2

Ubuntu 18.04版

python 3.6.8版
