【问题描述】:
我想在 Tensorflow lite 框架中使用 yolov4-tiny 来计算视频中跨越虚拟线的对象。
我使用以下命令转换了从 AlexeyAB's repo 训练的暗网权重:
python save_model.py --weights yolov4-tiny.weights --output ./checkpoints/yolov4-tiny-608-tf --input_size 608 --model yolov4 --tiny --framework tflite
python convert_tflite.py --weights ./checkpoints/yolov4-tiny-608-tf --output ./checkpoints/yolov4-tiny-608.tflite
你可以找到convert_tflite.py here
第一个命令使用 numpy==1.19.0 成功。但是,第二个显示这些错误:
loc("batch_normalization/moving_mean"): error: is not immutable, try running tf-saved-model-optimize-global-tensors to prove tensors are immutable
Traceback (most recent call last):
File "C:\Python37\lib\site-packages\tensorflow\lite\python\convert.py", line 213, in toco_convert_protos

enable_mlir_converter)
Exception: <unknown>:0: error: loc("batch_normalization/moving_mean"): is not immutable, try running tf-saved-model-optimize-global-tensors to prove tensors are immutable
During handling of the above exception, another exception occurred:

tensorflow.lite.python.convert.ConverterError: <unknown>:0: error: loc("batch_normalization/moving_mean"): is not immutable, try running tf-saved-model-optimize-global-tensors to prove tensors are immutable
我尝试过其他版本的 Tensorflow(2.2、2.3、2.4),但没有运气。 我该怎么办?
这里提出了一个类似的问题:Tensorflow Issue 44790
这是我的系统详细信息: 视窗 10、x64 GeForce GTX 1060 英伟达驱动程序 460.89 CUDA 11.0.3 CuDNN 8.0.5.39 Python 3.7.2
【问题讨论】:
-
我在这里找到了解决方案stackoverflow.com/questions/63652692/… 我将尝试使用 Ubuntu 运行转换以便能够使用 tf-nightly。
-
您能否将其发布为答案,我仍然遇到错误
-
这个我还没试过,但我找到了this one
