Hi,

I have a problem using the tempfile library on Spaces. This problem occurs sometimes.

I have [this](https://huggingface.co/spaces/tryolabs/norfair-demo) space that generates an output file that is a disk write and the main function returns the path to this file.

I know that if I do not use a tempfile, this works correctly, but I’d like to use tempfile to prevent generations of outputs in a local execution.

[This](https://huggingface.co/spaces/tryolabs/norfair-demo/blob/main/inference.py) is the function that generates the problem (temporary file lines are commented out to avoid errors).

And the logs when the execution fails are the following:

Traceback (most recent call last):  
File “/home/user/.local/lib/python3.8/site-packages/gradio/routes.py”, line 259, in run\_predict  
output = await app.blocks.process\_api(  
File “/home/user/.local/lib/python3.8/site-packages/gradio/blocks.py”, line 691, in process\_api  
predictions = self.postprocess\_data(fn\_index, predictions, state)

File “/usr/local/lib/python3.8/shutil.py”, line 435, in copy2  
copyfile(src, dst, follow\_symlinks=follow\_symlinks)  
File “/usr/local/lib/python3.8/shutil.py”, line 264, in copyfile  
with open(src, ‘rb’) as fsrc, open(dst, ‘wb’) as fdst:  
FileNotFoundError: [Errno 2] No such file or directory: ‘/tmp/tmpsp16mbfp/soccer532nbnksvotwvex0\_out.mp4’

As I mentioned earlier, this code runs perfectly in many situations, but sometimes finish with the above error.

Any suggestions to use the tempfile library capabilities properly on Spaces?

Thank you,  
Diego.

Hi @diegofernandezc !

You may have to copy your file into your temporary directory so that it doesn’t get deleted?

I think it’s fine if your demo doesn’t create a temporary file. Gradio will do that under the hood for you when your output component is `File`.

I looked for this on various websites including youtube and solved it using to verify the temp folder [path](https://thegeekpage.com/error-writing-a-temporary-file/).
