The following APIs should be backward compatible. Please test.
```python
class Linear(Layer):
def __init__(self, num_output, *args, bias=True, **kwargs):
# the following block is for backward compatibility.
# the old code will all Linear(2, 3), or (2, 3, False)
if len(args) > 0:
num_input = num_output
num_output = args[0]
if len(args) > 1:
bias = args[1]
self.num_output = num_output
self.bias = bias
class Conv2d(Layer):
def __init__(self,
out_channels,
kernel_size,
*args,
stride=1,
padding=0,
dilation=1,
group=1,
bias=True,
pad_mode="NOTSET",
**kwargs):
# the old code create the layer like: Conv2d(8, 16, 3)， or
Conv2d(8, 16, 3, stride=1)
# the following code block is for backward compatibility
if len(args) >0:
in_channel=out_channel
out_channel = kernel
kernel = args[0]
if len(args) > 1:
stride = args[1]
if len(args) > 2:
padding = args[2]
