No matching distribution found for pywin32==306 unstructured-inference docker error

I have installed the unstructured-inference by following command.
pip install unstructured-inference

And this package installed this (unstructured-inference==0.7.11)

Installing collected packages: pywin32, pytz, pyreadline3, mpmath, flatbuffers, antlr4-python3-runtime, urllib3, tzdata, typing-extensions, sympy, six, safetensors, regex, rapidfuzz, pyyaml, python-multipart, pypdfium2, pyparsing,

And I have a docker file to build a docker image:

# Use the official Python 3.10 image as the base image
FROM python:3.10-slim

# Set the working directory inside the container
WORKDIR /app

# Copy the requirements.txt file into the container
COPY requirements.txt /app/

# Install project dependencies
RUN pip install --no-cache-dir -r requirements.txt


# Copy the project code into the container
COPY . /app/

But this gives the following error:

#8 65.86 ERROR: Could not find a version that satisfies the requirement pywin32==306 (from versions: none)
#8 65.86 ERROR: No matching distribution found for pywin32==306

Start with requirements.txt and the provided Python 3.10 Dockerfile, then reproduce the failure with the Docker image build and inspect the pywin32 dependency resolution. Determine why pywin32==306 has no compatible distribution in this image and confirm that the requirements install completes successfully without breaking the stated dependency set.
