TDA4VM: numBatches = 6，模型转化不成功

还有一个问题：（模型都有相同的输入：288*512）在模型转化时，设置numBatches = 6，为什么resnet18和resnet34可以正确转化，而resnet50转化不成功呢

您好，您的问题我们需要升级到英文论坛寻求帮助，链接如下，有答复尽快给您：

您好，

请问您用的SDK版本是多少？从您分享的log来看似乎是8.2。

从9.0 SDK 起，对多核 DSP AM69A/TDA4VH 提供batch processing支持。 

在更换SDK9.0后，出现图中问题，应该是少了步骤，请问有最新的TI Deep Learning Product User Guide吗？

是否支持Ubuntu18.04

好的 谢谢您

您好，

升级SDK到9.0后仍不支持大尺寸多batch（1024*576,batch4输入）模型在板端的推理吗？WARNING: [TIDL_E_DATAFLOW_INFO_NULL] Network compiler returned with error or didn't executed, this model can only be used on PC/Host emulation mode, it is not expected to work on target/EVM.

执行如下操作：
