Nnvm.compiler.build fails for onnx models with Gemm Operation



I am facing error while compiling ONNX model with GEMM operation as below.

Could anyone help me with the issue.

test script:

import nnvm
import tvm
import onnx
import numpy as np
import tensorflow as tf
onnx_model = onnx.load(‘gemm3.onnx’)
sym, params = nnvm.frontend.from_onnx(onnx_model)
print(“debug symbols:”,sym.debug_str())
print("\n loading in nnvm done ")

Error Log :
