Error while running nngen.from_onnx()

Download the onnx file:
https://github.com/onnx/models/blob/master/vision/classification/mnist/model/mnist-1.onnx

And run Python code:

import os
import sys

sys.path.insert(0, os.path.dirname(os.path.dirname(
    os.path.dirname(os.path.abspath(__file__)))))

import nngen as ng

act_dtype=ng.int16
weight_dtype=ng.int8
bias_dtype=ng.int32
scale_dtype=ng.int8
disable_fusion=False
onnx_filename='mnist-1.onnx'

dtypes = {}
ng.from_onnx(onnx_filename,
             value_dtypes=dtypes,
             default_placeholder_dtype=act_dtype,
             default_variable_dtype=weight_dtype,
             default_constant_dtype=weight_dtype,
             default_operator_dtype=act_dtype,
             default_scale_dtype=scale_dtype,
             default_bias_dtype=bias_dtype,
             disable_fusion=disable_fusion)

the output is:
