bernhardklein opened a new issue #7909: URL: https://github.com/apache/tvm/issues/7909
The **bitserial conv2d** nhwc operator is not working if the next operation is **elementwise**, for example if the next operation is a ReLU. Corresponding [tvm discussion thread](https://discuss.tvm.apache.org/t/arm-bitserial-bug-cryptic-error-message/9757?u=bernhardklein) @comaniac pointed out that in the [TOPI schedule](https://github.com/apache/tvm/blob/main/python/tvm/topi/arm_cpu/bitserial_conv2d.py#L350-L443) the corresponding decision seems missing. In contrast for the [bitserial dense TOPI schedule](https://github.com/apache/tvm/blob/main/python/tvm/topi/arm_cpu/bitserial_dense.py#L190) a check for elemwise tag is included and the example snippet works with it.
