hTarget = dlhdl.Target("Xilinx",Interface="Ethernet",IPAddress="192.168.1.101");
hdlsetuptoolpath('ToolName', 'Xilinx Vivado', 'ToolPath', 'E:\Xilinx\Vivado\2024.2\bin\vivado.bat');
hW = dlhdl.Workflow(Network=net,Bitstream='zc706_single',Target=hTarget);
dn = compile(hW);
deploy(hW);

while I deploy the sigmoidlayer the output from ZC706 fpga the output is zero after sigmoidlayer, and the middle layers output's parameters is correct, it seems that the sigmoidlayers have some problems.How can I fix or it is a bug?
