Description
Hello,
I have a model with LSTM layer and I want to run this on a Raspberry4 with Coral USB accelerator connected.
In another post (#156) I read about the problems and with the additional command
USB_ENABLE_BULK_DESCRIPTORS_FROM_DEVICE=1
the program runs. However, with the customization, the model runs only half as fast as when I run it through the Raspberry CPU. Consequently, I currently have no advantage through the USB accelerator.Is there another way to do this in the meantime or is there no other solution yet?
In addition, I would be very interested to know why this command is/was needed, what exactly it does and why it results in this large latency.
