Error in expdist.py

[isazi]

There is an error in comparing RuntimeFailedConfig with other values in the expdist.py example.

best performing configuration:
block_size_x=32, block_size_y=1, tile_size_x=8, tile_size_y=2, use_shared_mem=0, time=0.541ms
Traceback (most recent call last):
  File "/home/alessio/src/kernel_tuner/examples/cuda/expdist.py", line 65, in <module>
    tune_expdist()
  File "/home/alessio/src/kernel_tuner/examples/cuda/expdist.py", line 46, in tune_expdist
    best_config1 = min(kernel1[0], key=lambda x:x['time'])
TypeError: '>' not supported between instances of 'numpy.ndarray' and 'RuntimeFailedConfig'

Thanks for letting me know! It's fixed now!

A similar error also happens in the create_results(_) function in class integration. The results_filtered will also miss to filter out the RuntimeFailedConfig and cause the same comparison error in the below code.

An improvement can be:

#filter results to only those that contain the objective
results_filtered = [item for item in results if objective in item and isinstance(item[objective], float)]
