e8035669 opened a new issue #14184: Cannot infer RNN symbol with mode=RNNMode::kRnn_tanh URL: https://github.com/apache/incubator-mxnet/issues/14184 ## Description (Brief description of the problem in no more than 2 sentences.) I'm using C++ interface. If I wanna create an RNN symbol with C++ factory function in `cpp-package/include/mxnet-cpp/op.h`, the generated function will always set all 4 inputs into the operator. But when I infer the symbols, RNN symbol expect exactly 3 input needed with `mode=RNNMode::kRnn_tanh`, and always fail to create `Executor`. I can create rnn symbol with `Operator` class, this can temporarily solve my problem. I think the shape checking is here. https://github.com/apache/incubator-mxnet/blob/5adb6fcfb3ea50c76d387e63ce367bbe8c3f18d3/src/operator/rnn-inl.h#L673-L677 And factory function in `op.h` is here. ```cpp inline Symbol RNN(const std::string& symbol_name, Symbol data, Symbol parameters, Symbol state, Symbol state_cell, uint32_t state_size, uint32_t num_layers, RNNMode mode, bool bidirectional = false, mx_float p = 0, bool state_outputs = false, dmlc::optional<int> projection_size = dmlc::optional<int>(), dmlc::optional<double> lstm_state_clip_min = dmlc::optional<double>(), dmlc::optional<double> lstm_state_clip_max = dmlc::optional<double>(), bool lstm_state_clip_nan = false) { static const char *RNNModeValues[] = { "gru", "lstm", "rnn_relu", "rnn_tanh" }; return Operator("RNN") .SetParam("state_size", state_size) .SetParam("num_layers", num_layers) .SetParam("mode", RNNModeValues[int(mode)]) .SetParam("bidirectional", bidirectional) .SetParam("p", p) .SetParam("state_outputs", state_outputs) .SetParam("projection_size", projection_size) .SetParam("lstm_state_clip_min", lstm_state_clip_min) .SetParam("lstm_state_clip_max", lstm_state_clip_max) .SetParam("lstm_state_clip_nan", lstm_state_clip_nan) .SetInput("data", data) .SetInput("parameters", parameters) .SetInput("state", state) .SetInput("state_cell", state_cell) .CreateSymbol(symbol_name); } ``` ## Environment info (Required) Oops, the output contains chinese. ``` text ----------Python Info---------- Version : 3.6.7 Compiler : GCC 8.2.0 Build : ('default', 'Oct 22 2018 11:32:17') Arch : ('64bit', 'ELF') ------------Pip Info----------- Version : 9.0.1 Directory : /usr/lib/python3/dist-packages/pip ----------MXNet Info----------- No MXNet installed. ----------System Info---------- Platform : Linux-4.15.0-45-generic-x86_64-with-Ubuntu-18.04-bionic system : Linux node : jeff-X555LJ release : 4.15.0-45-generic version : #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 ----------Hardware Info---------- machine : x86_64 processor : x86_64 架構： x86_64 CPU 作業模式： 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 每核心執行緒數： 2 每通訊端核心數： 2 Socket(s): 1 NUMA 節點： 1 供應商識別號： GenuineIntel CPU 家族： 6 型號： 61 Model name: Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz 製程： 4 CPU MHz： 1690.799 CPU max MHz: 2700.0000 CPU min MHz: 500.0000 BogoMIPS: 4393.55 虛擬： VT-x L1d 快取： 32K L1i 快取： 32K L2 快取： 256K L3 快取： 3072K NUMA node0 CPU(s)： 0-3 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault epb invpcid_single pti ssbd ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid rdseed adx smap intel_pt xsaveopt dtherm ida arat pln pts flush_l1d ----------Network Test---------- Setting timeout: 10 Timing for MXNet: https://github.com/apache/incubator-mxnet, DNS: 0.0582 sec, LOAD: 1.3309 sec.

Compile and run the code above. This code will fail at run time. 2. check the code at `#define FAIL_CODE` ## What have you tried to solve it? 1. Yes. I use `Operator` class to create symbol ``` cpp Symbol rnn = Operator("RNN") .SetParam("state_size", numRnnHidden) .SetParam("num_layers", numRnnLayer) .SetParam("mode", "rnn_tanh") .SetInput("data", input) .SetInput("parameters", rnnParam) .SetInput("state", rnnState) .CreateSymbol("rnn"); ```
