  • Hi, No problem, I'm glad to hear that! By the way, if you have the latest KL520 version (v2.2.0), you could also flash flash_image_solution_host_mipi.bin in KL520_SDK/firmware/utils/bin_gen and it would work as well.
    in How to run KL520 AI SOC Board Comment by Maria Chen May 8
  • Hi, It seems like the flash_image.bin isn't the correct file, because kdp2_flash_image.bin seems to include KDP2 FW, which is used for Kneron PLUS. Have you tried generating the firmware by using the workspace inside tiny_yolo_v3_host? https://www.k…

  • Hi Olivier, As long as the onnx model's operators are supported by KL720, it should be able to run. Supported operators list: Hardware Supported Operators - Document Center For a reference design for the chip, please contact our sales team. They wou…
    in Voice inference with KL720 Comment by Maria Chen April 25
  • Hi Jyoti, Usually, those who port their models would write their own postprocess, as they are the most familiar with their model. There are example tiny yolov3 and yolov5 postprocess functions in kneron_plus/python/example/utils, and for further tec…

  • 您好， 那個文檔用的toolchain是比較舊的版本。用最新的toolchain版本修改模型的話，如果opset是11或12，可以在base環境使用ONNX editor。如果是opset 13到18，可以在onnx1.13環境使用onnx.utils.extract_model (https://onnx.ai/onnx/api/utils.html)。

  • 您好， https://www.kneron.com/forum/discussion/comment/2259#Comment_2259 用onnx_convertor轉換工具來轉換pytorch等的模型成onnx，應該是可行的: 3. Floating-Point Model Preparation - Document Center 如果會失敗的話，可以試著在Kneron Toolchain (docker)裡…
    in Kneron AI-KL730 Comment by Maria Chen March 26
  • 您好， https://www.kneron.com/forum/discussion/comment/2258#Comment_2258 關於這些問題: 1 問題是因為toolchain轉換的過程會自動將input format設定成1W16C8B，所以pytorch2onnx_kneron.py不用修改喔。 2 現在，因為firmware的preprocess有出現問題，所以pre_proc_…
    in Kneron AI-KL730 Comment by Maria Chen March 26
  • 您好， 不好意思，我們找到原因了! 因為在Kneron Toolchain轉換模型時，會自動將input format設定成1W16C8B，所以您的model input format是1W16C8B: https://www.kneron.com/forum/uploads/498/X4BBLC6WKTNV.png 一般的input format是4W4C8B，而1W16C8B也可以支援，但…

  • 您好， 回答您最新的問題: 雖然nef model看起來沒有問題，但是KL730 generic inference應該要可以跑，但是會失敗。 YoloX當時是給KL720的範例，而且是Kneron PLUS 1.x的時候的文檔，目前沒有人在維護，那時候還沒有KL730。現在的Pytorch版本也一直在更新，導致model架…
    in Kneron AI-KL730 Comment by Maria Chen March 26
  • 您好， 我也有轉換您的onnx模型，雖然可以成功轉換成nef模型，跑KL730 generic inference卻也會失敗 (這個generic inference，用任何nef模型應該都要成功)。我認為可能是因為您之前說過的"编译出来的YOLOX模型与创建KL730单一模型示例图像格式不匹配"，因為…

  • Hi Jyoti, If you were talking about how in Kneron PLUS Python, the numpy arrays get truncated when you print out the results, you could try using: import sys import numpy numpy.set_printoptions(threshold=sys.maxsize) This would help print out all th…
    in Yolov8 output Data dumping in KL630 Comment by Maria Chen March 25
  • 您好， kneron_inference的結果會是numpy arrays，所以會需要您寫模型的postprocess來得到座標之後，才可以用顯示邊界框(display)的function，function的細節在/workspace/E2E_Simulator/python_flow/utils/utils.py裡面: https://www.kneron.com/forum/uploads/124/9W…
    in Kneron End to End Simulator v0.28.0 Comment by Maria Chen March 21
  • 您好， 不好意思回覆晚了，因為error code -7可能源於各種原因，我們會需要先確認模型沒有問題，然後再復現error和確認code，可以請您提供以下的資訊嗎? 謝謝您! -NEF model -Onnx model (確認有沒有不支持的operators) -firmware.tar -Kneron PLUS的code 如果是用自…
    in Kneron AI-KL730 Comment by Maria Chen March 21
  • 您好， 因為KL720不支援那些運算子，所以可能會需要請您用其他的模型。 如果這些運算子是在模型的最後面，也是可以將它們剪掉之後再自行寫postprocess把剪掉的運算子加回去，不過我們會建議用其他的模型。 Toolchain的話，請用最新的v0.28.0來轉換模型。您可以使用這個…

  • 您好， 只要KL720有支援ViT架構的onnx模型中的operators，照理說應該可以跑。請參照文檔裡的清單: Hardware Supported Operators - Document Center
    in ViT架構可以放進KL720嗎? Comment by Maria Chen March 5
  • Hi Franklin, I'm sorry for their lack of communication. Could you contact Jeffrey (jeffrey-yc.chen@kneron.us) instead and cc Brian just in case? Thank you!
    in Kneron toolchain not converting the YOLOv5s to KL520 Comment by Maria Chen February 26
  • 您好， 不好意思，這個文檔已不支援，所以不會再有新的文檔了。訓練出來的模型的operators，只要是KL730都有支持，就可以用Kneron Toolchain轉換成.nef模型。請參照: Hardware Supported Operators - Document Center 轉換的nef模型就可以在KL730上進行推論。
    in KL730 Kneron ModelZoo Comment by Maria Chen February 25
  • 您好， 這個文檔現在已不支援，需要麻煩您用之前的mmcv版本，要與您的CUDA版本對應。下載的command是: pip install mmcv-full==1.5.0 -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html 如下圖，不過是用mmcv-full，mmcv版本為1.…

  • Hi Nhleem, Edit: We've answered your question in another email.
    in Any linear algebra libraries available/tested on KL630? Comment by Maria Chen February 21
  • 您好， 無論是使用任何模型，我們都會建議您使用最新的Toolchain (v0.28.0)和SDK (v2.2.0) 版本。 KL720 SDK在官網上可以下載，而Kneron Toolchain可以用"docker pull kneron/toolchain:latest"指令來進行更新。

    in Kneron toolchain not converting the YOLOv5s to KL520 Comment by Maria Chen February 13
  • 您好， 是的，無論是用USB上傳和firmware燒錄都會需要先用NEF Combine組合兩個nef模型，然後再做燒錄喔。 NEF Combine的說明: 5. Compilation - Document Center 在KL720上用多個模型的範例: Create Multiple Model Example for KL720 - Document Center
    in KL720雙模型 Comment by Maria Chen February 13

    in 人體骨架偵測模型問題 Comment by Maria Chen February 12
  • 您好， 可以的，如果是要用USB上傳模型，大小的限制總共是75MB，而如果是在firmware上燒模型，限制總共是70MB。 https://www.kneron.com/forum/uploads/635/CQL637KGXO9U.png 參考文檔: Write Model To Flash - Document Center
