i was trying to write convolution layer in nnable using nnabla.parametric_functions, how do i provide the input channel dimensions to it ? I tried to look into nnabla docs at https://nnabla.readthedocs.io/en/latest/python/api/parametric_function.html?highlight=convolution#nnabla.parametric_functions.convolution Here is the code snippet: import numpy as np import nnabla as nn import nnabla.functions as F import nnabla.parametric_functions as PF input = nn.Variable([1,3,224,224])… Read More how to provide input channel dimension for nnabla convolution operation?
