python -m pip install -e .[inference-script]
ERROR: File “setup.py” or “setup.cfg” not found. Directory cannot be installed in editable mode: F:LTX_VIDEOLTX-Video
WARNING: You are using pip version 21.2.3; however, version 25.1.1 is available.
You should consider upgrading via the ‘F:LTX_VIDEOLTX-VideoenvScriptspython.exe -m pip install –upgrade pip’ command.

The error you’re seeing means pip can’t find a `setup.py` or `setup.cfg` file in the directory you’re trying to install from. That’s a deal-breaker for editable (`-e`) installs, which rely on those files to define the package.

### Let’s break this down:

#### 1. **Error: Missing `setup.py` or `setup.cfg`**
– Editable installs (`pip install -e`) are only valid for Python packages — i.e., directories that contain a `setup.py`, `setup.cfg`, or a `pyproject.toml` file with proper config.
– You’re running it in `F:LTX_VIDEOLTX-Video`, but that folder doesn’t have any of the necessary files.

**Fix:**
– If you’re developing a Python package, make sure the folder has a `setup.py`, `setup.cfg`, or `pyproject.toml`.
– If you’re not writing a package and just want to run code, you don’t need `-e`. Just run the scripts or install dependencies directly.

#### 2. **Typo in the extras syntax**
You’re using:
“`bash
-e .[inference-script]
“`
But it should be:
“`bash
-e .[inference-script]
“`
Backslashes aren’t needed (and might be misinterpreted by the shell).

#### 3. **Warning: Outdated pip**
Your pip is ancient by internet standards.

**Update it:**
“`bash
F:LTX_VIDEOLTX-VideoenvScriptspython.exe -m pip install –upgrade pip
“`

—

### Summary:
– ✅ Remove the backslashes.
– ✅ Ensure you’re in a valid Python package folder (with `setup.py`, etc.).
– ❌ Don’t use `-e` unless you’re working on a package.
– 🚀 Update pip.
