קל לארגן דפים בעזרת אוספים
אפשר לשמור ולסווג תוכן על סמך ההעדפות שלך.
מגדיר מחלקות לבנייה, שמירה, טעינה וביצוע של מודלים של TensorFlow.
אזהרה : ה-API הוא כרגע ניסיוני ואינו מכוסה על ידי ערבויות היציבות של TensorFlow API . ראה README.md להוראות התקנה.
הדוגמה של LabelImage מדגימה שימוש ב-API זה כדי לסווג תמונות באמצעות רשת נוירונים קונבולוציונית מיומנת מראש של ארכיטקטורת Inception . זה מדגים:
- בניית גרף: שימוש במחלקה OperationBuilder לבניית גרף לפענוח, שינוי גודל ונימול של תמונת JPEG.
- טעינת מודל: שימוש ב-Graph.importGraphDef() כדי לטעון מודל Inception מאומן מראש.
- ביצוע גרף: שימוש ב-Session כדי לבצע את הגרפים ולמצוא את התווית הטובה ביותר לתמונה.

See [README.md](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/java/README.md)\nfor installation instructions.\n\nThe [LabelImage](https://www.tensorflow.org/code/tensorflow/java/src/main/java/org/tensorflow/examples/LabelImage.java)\nexample demonstrates use of this API to classify images using a pre-trained [Inception](http://arxiv.org/abs/1512.00567) architecture convolutional neural network.\nIt demonstrates:\n\n- Graph construction: using the OperationBuilder class to construct a graph to decode, resize and normalize a JPEG image.\n- Model loading: Using Graph.importGraphDef() to load a pre-trained Inception model.\n- Graph execution: Using a Session to execute the graphs and find the best label for an image.\n\n###
