I am very new to docker. I can successfully run python files on my machine however Docker is unable to recognize the pandas library.

Here is my Docker file:

FROM python
WORKDIR /app
COPY . /app
CMD ["python3", "fisherlog_corrected.py"]

The error message is as follows:

Traceback (most recent call last):
  File "/app/fisherlog_corrected.py", line 5, in <module>
    import pandas as pd
ModuleNotFoundError: No module named 'pandas'

How to solve this?
