Support examples for gr.Gallery

Describe the bug

Hi Gradio Development Team,

I suspect there may be an issue with the Examples mechanism when using the gr.Gallery component. The same Examples implementation works perfectly with the gr.Image component. Here's a detailed explanation of the issue:

Recently, I updated my Gradio application by replacing the gr.Image component with gr.Gallery. However, this resulted in a PermissionError: [Errno 13] Permission denied: 'C:\\my\\path'.

Upon investigation, it appears that the issue may be related to the component.as_example(ex) function in gradio\components\dataset.py.

To debug, I added a print statement in the __init__ method of dataset.py. Below are the console logs for comparison:

When using gr.Image, the console log shows:

component: ex:power.jpg component.as_example(ex):path='power.jpg' url=None size=None orig_name='power.jpg' mime_type=None is_stream=False meta={'_type': 'gradio.FileData'}

When using gr.Gallery, the console log shows:

component: ex:power.jpg component.as_example(ex):root=[GalleryImage(image=FileData(path='p', url=None, size=None, orig_name='p', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='o', url=None, size=None, orig_name='o', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='w', url=None, size=None, orig_name='w', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='e', url=None, size=None, orig_name='e', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='r', url=None, size=None, orig_name='r', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='.', url=None, size=None, orig_name='', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='j', url=None, size=None, orig_name='j', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='p', url=None, size=None, orig_name='p', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None), GalleryImage(image=FileData(path='g', url=None, size=None, orig_name='g', mime_type=None, is_stream=False, meta={'_type': 'gradio.FileData'}), caption=None)] Traceback (most recent call last): File "C:\my\path\app.py", line 469, in main() File "C:\my\path\app.py", line 449, in main gr.Examples( File "C:\my\path\venv\lib\site-packages\gradio\helpers.py", line 56, in create_examples examples_obj = Examples( File "C:\my\path\venv\lib\site-packages\gradio\helpers.py", line 264, in __init__ self.dataset = components.Dataset( File "C:\my\path\venv\lib\site-packages\gradio\component_meta.py", line 179, in wrapper return fn(self, **kwargs) File "C:\my\path\venv\lib\site-packages\gradio\components\dataset.py", line 117, in __init__ processing_utils.move_files_to_cache( File "C:\my\path\venv\lib\site-packages\gradio\processing_utils.py", line 516, in move_files_to_cache return client_utils.traverse( File "C:\my\path\venv\lib\site-packages\gradio_client\utils.py", line 1009, in traverse new_obj.append(traverse(item, func, is_root)) File "C:\my\path\venv\lib\site-packages\gradio_client\utils.py", line 1004, in traverse new_obj[key] = traverse(value, func, is_root) File "C:\my\path\venv\lib\site-packages\gradio_client\utils.py", line 1000, in traverse return func(json_obj) File "C:\my\path\venv\lib\site-packages\gradio\processing_utils.py", line 490, in _move_to_cache temp_file_path = block.move_resource_to_block_cache(payload.path) File "C:\my\path\venv\lib\site-packages\gradio\blocks.py", line 347, in move_resource_to_block_cache temp_file_path = processing_utils.save_file_to_cache( File "C:\my\path\venv\lib\site-packages\gradio\processing_utils.py", line 277, in save_file_to_cache temp_dir = hash_file(file_path) File "C:\my\path\venv\lib\site-packages\gradio\processing_utils.py", line 206, in hash_file with open(file_path, "rb") as f: PermissionError: [Errno 13] Permission denied: 'C:\\my\\path'

Could you please help investigate and confirm this behavior? Thank you!

Reproduction

import gradio as gr

def main():
    with gr.Blocks() as demo:
        with gr.Column():
            #image = gr.Image(type="pil", image_mode="RGBA", label="Input")
            gallery = gr.Gallery(columns=5, rows=5, show_share_button=False, interactive=True, height="500px", label="Input")

        gr.Examples(
            [["power.jpg"]], 
            inputs=[
                gallery,
            ],
        )

    demo.queue(max_size=10)
    demo.launch(inbrowser=True)

if __name__ == "__main__":
