I have uploaded file but its showing error

→ ERROR: process “/bin/sh -c pip install --no-cache-dir -r /tmp/requirements.txt” did not complete successfully: exit code: 1

If I diagnose just by log:

## What this log is actually telling you

### 1) “cache miss …” is not the error

Those lines are Docker/BuildKit progress output saying the builder **didn’t reuse cached layers** (so it re-ran the steps). Your Space can still succeed with “cache miss” lines. Your page shows the same pattern. ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud "Credit Card Fraud - a Hugging Face Space by sdhoot"))

### 2) “Failed to retrieve error logs: SSE is not enabled” means “the UI can’t show the real failure”

SSE = Server-Sent Events (the streaming mechanism Spaces uses to fetch logs). When SSE is “not enabled” (or otherwise unavailable), you often see only the _outer_ build scaffolding, not the actual pip/OS error line. This shows up in unrelated Spaces issues, so it’s commonly **a logging/infra limitation** , not the root cause. ([Hugging Face](https://huggingface.co/spaces/jamesliu1217/EasyControl_Ghibli/discussions/24 "Space error: Failed to retrieve error logs: SSE is not enabled"))

## Background: how Gradio Spaces are built (why your output looks like this)

In a Gradio Space, Hugging Face’s build uses a base image and runs steps like:

1. install a Gradio runtime (plus extras) and “spaces” tooling (your log shows `pip install … gradio[oauth,mcp]==6.5.1 … spaces`) ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud "Credit Card Fraud - a Hugging Face Space by sdhoot"))
2. copy your repo into the container (`COPY … /app`) ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud "Credit Card Fraud - a Hugging Face Space by sdhoot"))
3. install your `requirements.txt` (`pip install -r requirements.txt`) ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud "Credit Card Fraud - a Hugging Face Space by sdhoot"))

If step (3) tries to **change core runtime packages** (especially `gradio`), pip can fail or produce a broken environment.

* * *

## Most likely cause in _your_ repository: Gradio version conflict

Your repo config currently sets **Gradio 6.5.1** via the Space YAML:

- `sdk: gradio`
- `sdk_version: 6.5.1` ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/README.md "README.md · sdhoot/credit\_card\_fraud at main"))

But your `requirements.txt` pins **Gradio 4.44.0** :

- `gradio==4.44.0` ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/requirements.txt "requirements.txt · sdhoot/credit\_card\_fraud at main"))

That is a direct mismatch. In Gradio Spaces, Hugging Face explicitly documents that the Gradio version should be controlled via `sdk_version`. ([Hugging Face](https://huggingface.co/docs/hub/en/spaces-sdks-gradio "Gradio Spaces"))  
And there are forum threads describing how pinning Gradio (or related core deps) in `requirements.txt` can be overridden or can cause conflicts during rebuilds. ([Hugging Face Forums](https://discuss.huggingface.co/t/huggingface-spaces-not-updating-packages-from-requirements-txt/92865 "Huggingface spaces not updating packages from ..."))

### What failure would this typically create?

Common outcomes:

- **pip dependency resolution failure** (“cannot install X and Y together”, “ResolutionImpossible”, etc.)
- or pip succeeds but your runtime becomes inconsistent (less common, but worse)

Because your Space can’t stream the real logs (SSE error), you don’t see the exact pip line—but the mismatch above is the most concrete, repo-specific explanation.

* * *

## Fixes / workarounds (in the order I’d try)

### Option A (recommended): Keep Gradio 6.5.1 and remove Gradio from `requirements.txt`

1. Edit `requirements.txt` to remove the `gradio==4.44.0` line, leaving only your app deps (pandas/numpy/scikit-learn).
2. Keep `sdk_version: 6.5.1` in `README.md`.

Why this is the clean path:

- Gradio Spaces docs: change Gradio version through `sdk_version`. ([Hugging Face](https://huggingface.co/docs/hub/en/spaces-sdks-gradio "Gradio Spaces"))
- Dependency guidance: use `requirements.txt` for your packages. ([Hugging Face](https://huggingface.co/docs/hub/en/spaces-dependencies "Handling Spaces Dependencies in Gradio Spaces"))
- Community reports: pinning Gradio in requirements can be problematic in Gradio Spaces. ([Hugging Face Forums](https://discuss.huggingface.co/t/huggingface-spaces-not-updating-packages-from-requirements-txt/92865 "Huggingface spaces not updating packages from ..."))

### Option B: If you want Gradio 4.44.0, make the Space YAML match

Set `sdk_version: 4.44.0` in `README.md` so both YAML and `requirements.txt` agree. Gradio Spaces are designed for this knob. ([Hugging Face](https://huggingface.co/docs/hub/en/spaces-sdks-gradio "Gradio Spaces"))

### Option C: Force a clean rebuild when you change dependency strategy

Use **“Factory reboot this space”** in the Space Settings. This is specifically recommended to rebuild “without using cached requirements.” ([Hugging Face Forums](https://discuss.huggingface.co/t/can-i-force-rebuild-a-huggingface-space/18419 "Can I force rebuild a huggingface space?"))

### Option D: Switch to Docker Space if you need total control

If you want deterministic installs (and to avoid managed Gradio install layers), use Docker Spaces (`sdk: docker`) and manage everything in a `Dockerfile`. ([Hugging Face](https://huggingface.co/docs/hub/en/spaces-sdks-docker "Docker Spaces"))

## How to diagnose when logs are hidden by the SSE issue

Even without server logs, you can validate the _most likely_ failure locally:

```bash
python -m venv .venv
source .venv/bin/activate
pip install -U pip
pip install gradio==6.5.1
pip install -r requirements.txt

```

If pip errors, you’ll see the exact conflict immediately. (If it succeeds locally, then the next suspect is platform-side/build infra.)

Also: if “SSE is not enabled” persists across restarts/factory reboot, it can be an infra-side issue (multiple users report it independently of their code). ([Hugging Face Forums](https://discuss.huggingface.co/t/please-fix-sdxl-space-not-loading/170806 "Please fix SDXL space not loading"))

* * *

## After the build succeeds: a runtime error you’ll likely hit next (separate from build)

Your `app.py` contains invalid Python format specifiers like `:.1 f` and `:.2 f` (note the space). That will raise a runtime exception when those strings are formatted. Example lines show `({y.mean()*100:.1 f}%)` and `{accuracy*100:.2 f}%`. ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/app.py "app.py · sdhoot/credit\_card\_fraud at main"))  
Fix: remove the spaces → `:.1f`, `:.2f`, `:,.2f`.

* * *

## Minimal “do this now” change set

1. Remove `gradio==4.44.0` from `requirements.txt`. ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/requirements.txt "requirements.txt · sdhoot/credit\_card\_fraud at main"))
2. Keep `sdk_version: 6.5.1` in README. ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/README.md "README.md · sdhoot/credit\_card\_fraud at main"))
3. Factory reboot. ([Hugging Face Forums](https://discuss.huggingface.co/t/can-i-force-rebuild-a-huggingface-space/18419 "Can I force rebuild a huggingface space?"))
4. Fix `:.1 f` → `:.1f` etc. in `app.py` to avoid the next runtime crash. ([Hugging Face](https://huggingface.co/spaces/sdhoot/credit_card_fraud/blob/main/app.py "app.py · sdhoot/credit\_card\_fraud at main"))
