ModuleNotFoundError in Docker

[giuqoob]

I've been trying to take working code from my Windows PC to Docker without success. In Docker the installation process goes fine without error but later in the code I get this simple error

File "/code/table.py", line 35, in <module>
    import fitz
ModuleNotFoundError: No module named 'fitz'

Here's a snippet from my Dockerfile

FROM python:3.10
WORKDIR /code
COPY ./requirements.txt ./
RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt

# install PyMupdf
RUN pip install pymupdf

COPY . .

CMD ["python", "./run.py"]

And from my docker-compose.yml

build: .
container_name: ocr
command: python ./run.py
volumes:
  - .:/code
  - type: bind
    source: "C:/Program Files/Tesseract-OCR/tessdata"
    target: /code/tessdata

Any ideas? Anyone had success using PyMuPDF in Docker? Basically what my project is doing is taking some PDF files, moving them around and reading them. If reading them doesn't work, I do OCR first and go from there.

Alright so this was a docker-related issue after all. When building the image it was referencing a huge cache every time regardless of me destroying the previous images. Once I deleted the cache, it built the image from scratch and now it works.
