Hi, I have a problem with Gradio and HuggingFace Spaces. The problem is that when I try to set examples in this way: ```auto intput_components = [ input_video, dd_model, features, dd_track_points, slide_threshold, ] output_components = "playablevideo" example_list = [["examples/" + example] for example in os.listdir("examples")] iface = gr.Interface( fn=inference, inputs=intput_components, outputs=output_components, examples=example_list, ) iface.launch() ``` where each element of the input\_components list is a Gradio component. When I run this code locally I do not have any problems showing the examples (mp4 videos). I have Git LFS set properly. This is the error that the logs show me when I run this code on Spaces, but if I remove the attribute examples there is no error in that execution. For this reason, I do not understand the error and there is any possibility of a bug on the deploy process. ```auto Traceback (most recent call last): File "app.py", line 40, in iface = gr.Interface( File "/home/user/.local/lib/python3.8/site-packages/gradio/interface.py", line 626, in __init__ self.examples_handler = Examples( File "/home/user/.local/lib/python3.8/site-packages/gradio/examples.py", line 56, in create_examples utils.synchronize_async(examples_obj.create) File "/home/user/.local/lib/python3.8/site-packages/gradio/utils.py", line 364, in synchronize_async return fsspec.asyn.sync(fsspec.asyn.get_loop(), func, *args, **kwargs) File "/home/user/.local/lib/python3.8/site-packages/fsspec/asyn.py", line 96, in sync raise return_result File "/home/user/.local/lib/python3.8/site-packages/fsspec/asyn.py", line 53, in _runner result[0] = await coro File "/home/user/.local/lib/python3.8/site-packages/gradio/examples.py", line 208, in create await self.cache_interface_examples() File "/home/user/.local/lib/python3.8/site-packages/gradio/examples.py", line 246, in cache_interface_examples prediction = await self.predict_example(example_id) File "/home/user/.local/lib/python3.8/site-packages/gradio/examples.py", line 263, in predict_example predictions = await anyio.to_thread.run_sync(self.fn, *processed_input) File "/home/user/.local/lib/python3.8/site-packages/anyio/to_thread.py", line 31, in run_sync return await get_asynclib().run_sync_in_worker_thread( File "/home/user/.local/lib/python3.8/site-packages/anyio/_backends/_asyncio.py", line 937, in run_sync_in_worker_thread return await future File "/home/user/.local/lib/python3.8/site-packages/anyio/_backends/_asyncio.py", line 867, in run result = context.run(func, *args) TypeError: inference() missing 4 required positional arguments: 'model', 'features', 'track_points', and 'model_threshold' ``` ---

Hello @diegofernandezc, Do you still have issues with your space ? Is so could you provide the link to the space ? ---

Hello @chris-rannou This is the space: [Norfair - a Hugging Face Space by tryolabs](https://huggingface.co/spaces/tryolabs/norfair-demo) ---

I can confirm the examples files are included in the deployed space. I tried and submit one of them `norfair_demo.mp4` which worked as expected. Did you check the gradio version locally matches the one for the space ? Could you try adding the examples with an absolute path ? (`/home/user/app/examples`) ---

@diegofernandezc Can you try setting `cache_examples=False` in the interface init? This is a bug in gradio. By default on spaces, gradio will try to cache the example outputs but that will not work if only some of the inputs are provided as examples. ---

Hi again @chris-rannou @freddyaboulton I fixed this problem by setting default arguments to the function called by the interface. This function fails with `cache_examples=True` because when the app starts it doesn’t receive any arguments to run over the example videos. Greetings. ---

Thanks @diegofernandezc ! I filed this github issue a couple of days ago to provide a clearer error message in this case: [Interfaces which provide partial examples will crash on Spaces · Issue #2239 · gradio-app/gradio · GitHub](https://github.com/gradio-app/gradio/issues/2239)
