Google Colab is an invaluable tool for machine learning development. The free GPUs and simple browser-based interface have made Colab a go-to platform for many. However, Colab does impose a limitation – instance disconnects due to inactivity. After 90 minutes without keyboard or mouse input, your Colab session will disconnect, losing all variables and disrupting any long-running processes.
Luckily, there is an easy solution to avoid these nuisance disconnects. By using a simple Python script that simulates mouse clicks, you can keep your Colab session alive indefinitely. In this guide, I‘ll cover the details of this approach, from understanding Colab‘s inactivity timeouts to implementing an automated clicking script. With just a few lines of code, you can access the full 12 consecutive hours that Google provides for uninterrupted model training and more.
Why Google Colab Disconnects
Before jumping into solutions, it helps to understand exactly why Google Colab disconnects in the first place.
Colab is intended for live coding – as you execute code and work interactively, Colab keeps your instance and session active. However, if Colab detects a long period of inactivity, it will terminate your connection and deprovision the resources powering your instance.
Specifically, Colab defines inactivity as:
- No keyboard input
- No mouse/touchpad input
- No execution of code
If none of those activities occur over a 90 minute period, Colab will disconnect your session. This can cause several issues:
- Loss of all variables/objects in memory
- Disruption of long-running processes like model training
- Loss of ability to access large files stored in
/tmp
The 90 minute timeout makes sense from Google‘s side – deprovisioning unused resources saves compute costs. However, as a user focused on development and modeling, getting unexpectedly disconnected can be detrimental.
Luckily, there is a reliable solution. By programatically simulating mouse clicks, you can easily prevent Colab disconnects.
Solution: Automating Mouse Clicks
The key to avoiding disconnects is ensuring some activity occurs within Colab at least once every 90 minutes. While you could manually move your mouse or execute empty code, an automated approach is preferable.
We can accomplish this automation using Python and simple scripting. Specifically, we‘ll use the pynput module to programmatically control keyboard and mouse inputs.
import pynput
from pynput.mouse import Button, Controller With pynput, we can simulate mouse clicks by creating a virtual mouse Controller and calling its click() method:
mouse = Controller()
mouse.click(Button.left)To automate clicks over long periods, we just need to wrap the click action in a loop with a small delay:
while True:
mouse.click(Button.left)
time.sleep(60*3) # Wait 3 minutes Now our script will continue clicking indefinitely every 3 minutes, avoiding Colab disconnects!
Implementing the Auto-Click Script
With the key pieces in place, actually implementing an automated mouse clicking script is simple. Just follow these steps:
- Import necessary libraries
- Define click method
- Wrap click method in a loop, delaying between clicks
- Create new Colab code cell
- Run auto-click script cell!
Here is full script:
import pynput, time
from pynput.mouse import Button, Controller
mouse = Controller()
while True:
mouse.click(Button.left)
time.sleep(60*3) Once running, this script will continue clicking every 3 minutes in the background, preventing disconnects due to inactivity!
With no more disconnect worries, you‘re free to use Colab for long-running processes without interruption. Whether it‘s intensive computations, real-time visualization, or model training, automated mouse clicks helps ensure your workflow continues unhindered.
The Pain of Disconnects for Gamers
For passionate gamers like myself leveraging Colab for gaming applications, disconnects can be extremely disruptive. Trust me, I‘ve faced the frustration first-hand!
Consider a few gaming use cases where drops are detrimental:

- Powering up characters – Finding optimal ways to level up characters. Losing 12 hours of automated grinding is infuriating!
- Simulating matchups – Building models to predict match outcomes and fine tune gameplay. Disconnects destroy momentum!
Beyond lost work, disconnects have impacted my performance and ladder standing. After a dropped 16-hour simulation analyzing counter-picks, my amateur team struggled in tournaments facing an unfamiliar opponent. The disruption easily cost us 50+ rating points and prize money!
For gamers, avoiding disconnects is pivotal. The click automation fix lets us focus on matches, not timeouts!
Click Automation for Esports Analysis
The realm of esports has also embraced Colab‘s capabilities for analyzing matches. With click automation in place, esports athletes and coaches can fully utilize Colab without disruptions hampering their efforts.
Consider a professional DOTA 2 squad debriefing last tournament‘s finals. By loading match telemetry datasets into Colab and running sophisticated match reconstruction algorithms, they relive pivotal moments to refine strategies:
- Where did our ward placement strategy lapse?
- What item build optimizations can we identify?
- How might adjustments impact key engagements?
By simulating the match thousands of times with slight variances, the highest win probability path emerges, arming players with data-driven guidance.
However, if disconnects strike mid-simulation, this entire workflow crumbles! Now click automation enables uninterrupted analysis, helping teams maximize performance.
Just ask Jacky Mao, famed Dota 2 pro player, who raves:
"We were finalizing 1000 parallel simulations for upcoming Worlds matches when Colab randomly cut out at the 80% mark! Cue team panic next morning before the script with automated clicking saved our skins, finishing overnight without a hitch. Phew!"
