how can I use Netron to BLAI model file. do we have some doc about NPU BLAI-100 and the BLAI -model .

ZoneMR commented 6 months ago

Sadly the .blai models generated from Maixhub have been broken for some time (I believe they upgraded tensorflow to use per-channel quantisation which is not supported by the blai toolchain). There does not appear to be any appetite from Sipeed nor Bouffalo to provide up-to-date tools or documentation for the NPU on the BL808, which is a shame.
