Hi,
My autotvm.template has the following signature,
@autotvm.template
def convolution(dtype):
and I call the template with the following task,
task = autotvm.task.create(convolution, args=('float32'), target='llvm')
which results in the following error,
Traceback (most recent call last):
File "fp_tvm_tuner.py", line 236, in <module>

TypeError: convolution() takes 1 positional argument but 7 were given
It looks like ‘float32’ is read as 7 arguments (each character as an argument, i.e., if I pass ‘float322’, it will read 8 arguments) instead of a single string. Has anyone noticed this behavior before?
Also, I would like to know how to handle a template that doesn’t take any arguments. What should be the value of args to the autotvm.task.create function in that case? Documentation specifies args as a List object but apparently an empty list/iterable (i.e, args = [] or args=()) again throws the following error.
