  • 你好， Kneo-Pi是使用Arch linux的GUI OS，基本上可以視為一台小電腦，若有不同台KNEO Pi要相互通訊，使用網路會是最為便捷的作法

  • Hello, Kneron Academy從2021年後就停止更新了，裡面所用的架構host_lib也都不再支援了，目前已經全面換成新架構PLUS，也沒有要再支援Kneron Academy的規劃。 若是想了解KL520的相關用法的話，建議可以從C版本的PLUS起步，可以參考文件 https://doc.kneron.com/docs/#p…

  • Hello, 我這邊在720上透過直接修改kl720_demo_generic_image_inference內的模型路徑跑你提供的models_720.nef，看起來是可以正常推論的 (使用PLUS 3.1.2，並事先將720燒入/kneron_plus_v3.1.2/kneron_plus/res/firmware/KL720/中的fw.bin https://www.kneron.com/forum…

  • HW preprocess的部分主要是針對傳統圖片來進行處理，所以會以4W4C8B為主，其餘的格式或許可以局部支援，但效果最好的會是4W4C8B，若要針對處理的話建議以此格式為主 convert_onnx_data_to_npu_data的部分主要是針對浮點轉定點的部分，確保輸入的資料符合KL730的NPU架構…

  • 若希望使用HW來完成標準格式的前處理，建議可以讓模型的input format為4W4C8B，可透過<Input Format (Optional)>來設定 https://doc.kneron.com/docs/#toolchain/manual_5_nef/#53-nef-combine-optional 但要指定成4W4C8B的話，模型須滿足下面條件 first layer要…

  • Hello, KL730DemoGenericDataInference.py與KL730DemoGenericImageInference.py.py這兩個範例的差異在於，模型的前處理是否透過KL730中的HW來進行加速運算。 從你使用KL730DemoCamGenericImageInferenceDropFrame.py會遇到錯誤來看，有可能你的模型前處理並非標準的格…

  • 要比較models_730.nef與pth，請先在toolchain上透過ktc.kneron_inference()分別對ONNX與NEF模型推論，並確認兩者使用完全相同的流程(preprocess, postprocess. etc..)，僅有模型的差異，來比較兩者答案是否都有符合您的預期 在因為PLUS上容易因為前後處理與原本有差異…
