This is my Dockerfile.

FROM python:3.7
EXPOSE 8501
WORKDIR /app
COPY requirements.txt ./requirements.txt
RUN pip install -r requirements.txt
COPY . .
CMD streamlit run app.py

This is my requirements.txt.

pandas==1.0.3
numpy==1.18.3
streamlit==0.58.0
plotly==4.6.0
fbprophet==0.6
pybase64

Error that I got:

What is wrong? Thank you so much.

Hi @LLL, welcome to the Streamlit community!

Without trying this myself, I suspect its one of two problems. One, the pip resolver might not be working correctly to build your environment. You could try to remove the version number from numpy, in case fbprophet is looking for a specific numpy version. The second possibility could be the bigger issue of distributing compiled code using pip, which has historically been an issue (and why conda was created, to make sure the build toolchain for numpy and the like worked everywhere).

But try removing the numpy version first from requirements.txt.

I removed the version number from numpy.

pandas==1.0.3
numpy
streamlit==0.58.0
plotly==4.6.0
fbprophet==0.6
pybase64

I also tried including pystan.

pandas==1.0.3
numpy
streamlit==0.58.0
plotly==4.6.0
pystan==2.19.1.1
fbprophet==0.6
pybase64

In both cases, I’m getting back the same error. What else should I try?

The problem looks to be that fbprophet needs numpy in order to install not simply run.

I think you will need to run a pip install numpy (with version if you’d like) first, then install the rest of the dependencies.

EXPOSE 8501
WORKDIR /app
RUN pip install numpy==1.18.3
COPY requirements.txt ./requirements.txt
RUN pip install -r requirements.txt
COPY . .
CMD streamlit run app.py```

Had the very same issue and Ian Calvert’s suggestion solved it.
I also included the pandas dependency as well, as fb prophet in forecaster.py
imports numpy as well as pandas, so the dockerfile would look something like:

EXPOSE 8501
WORKDIR /app
RUN pip install numpy==1.18.5
RUN pip install pandas==1.0.4
RUN pip install convertdate==2.2.1
RUN pip install LunarCalendar==0.0.9
RUN pip install holidays==0.10.2
RUN pip install matplotlib==3.2.1
RUN pip install plotly==4.8.1
RUN pip install pystan==2.19.1.1
COPY requirements.txt ./requirements.txt
RUN pip install -r requirements.txt
COPY . .
CMD streamlit run app.py```

After that everything worked like a charm. To be honest I don’t know whether this is correct way to do it, however it works.

Welcome to the community @samlidippos, and thanks for sharing! That doesn’t look unreasonable to me.
