Timeout issue

[chintan-donda]

I'm developing a Gradio based application. I need to use googletrans lib for language translation.
googletrans lib internally installs httpx. This library uses httpx for HTTP requests so HTTP/2 is supported by default.

My application uses machine learning model inference which takes more than 7-8 seconds sometimes.
After inference, the application sends the response to Gradio front-end which gets showcased in the localhost.

Issue:
Because of default Timeout = 5.0 seconds in httpx, it is causing Gradio application failed to receive the response.

When I change this line to 10 seconds, it works fine.

How can we overwrite this value? Is there any fix?

Hi! You don't have access to the httpx client, but you'd like to change the timeout, correct? Could you please provide more information and possibly some code examples so that we can better understand your problem?

I don't want the access to httpx client.
Rather I want to change the timeout something like:

import httpx
from httpx._config import Timeout
httpx._config.DEFAULT_TIMEOUT_CONFIG = Timeout(timeout=30.0)
print(f"httpx DEFAULT_TIMEOUT_CONFIG set to: {httpx._config.DEFAULT_TIMEOUT_CONFIG}")

This prints on console that DEFAULT_TIMEOUT_CONFIG = 30.0
But this config doesn't get applied globally.

When I run my application, I still get the timeout issue.

I don't think it's a reliable solution; instead, find some api that allows you to change the client's timeout.

In your case, httpx client is used by "googletrans" library, right?

yes, "googletrans" library uses httpx client.

I've found something like this from here:

client = httpx.Client(timeout=10.0)
with httpx.Client(timeout=20.0) as client:
    client.get("http://example.com/api/v1/example", timeout=None)

But not working out. For this, I need to make changes inside googletrans lib. Not feasible.

If you do this before importing the "googletrans" library, your example should work.

[karpetrosyan]

Alternatively, you can import that library, then find the client if it's globally defined and change the timeout property.

Tried this, but doesn't work either:

from googletrans import Translator
# Init the Google API translator
translator = Translator(timeout=30.0)

Only solution for now I see is manually update this line with higher number.
Any better suggession?

[karpetrosyan]

This question is more about "googletrans" than httpx, and I only see that solution if there is no public API to do so.

[chintan-donda]

May be yes. But if we can change httpx.DEFAULT_TIMEOUT_CONFIG to configurable value globally, the issue is solved. But couldn't able to do it till now via programatically in Python. Changing manually works.

[karpetrosyan]

Try this

from googletrans import Translator
import httpx
translator = Translator(timeout=httpx.Timeout(0.00000001))

translator.client.get("https://google.com")  # timeout error

Worked for me
