# === STEP 1: Manually install gradio and a compatible websockets version ===
# This step ensures that a compatible version of websockets is installed
# without any interference from other packages.
RUN pip install --no-cache-dir "gradio==4.25.0" "websockets>=10.0,<13.0"

# Copy requirements.txt
COPY requirements.txt .

# === STEP 2: Install remaining dependencies ===
# Now install the rest of your dependencies. These are less likely to
# cause issues with gradio since it's already installed.
RUN pip install --no-cache-dir -r requirements.txt

# === FINAL STEP: A check to ensure websockets is present ===
RUN python -c "import websockets.asyncio.client; print('✅ websockets.asyncio.client is available')"
