Mamba env installation fails #287

Closed hacky1610 closed 1 year ago

hacky1610 commented 1 year ago

Describe the bug The installation of the python packages by means of the ml4t.yml file is failing. I am getting the error:

Encountered problems while solving:

package numpy-1.19.1-py36hbc911f0_0 requires mkl >=2019.4,<2021.0a0, but none of the providers can be installed
package libsqlite-3.40.0-h753d276_0 requires libzlib >=1.2.13,<1.3.0a0, but none of the providers can be installed

To Reproduce

Create a DOCKERFILE inside of the installation folder. The content should be

Start from a core stack version

FROM jupyter/datascience-notebook:python-3.8

Install in the default python3 environment

COPY ./linux/ml4t.yml /var/tmp/ml4t.yml RUN conda create -n ml4t python=3.8 RUN mamba env update -n ml4t -f /var/tmp/ml4t.yml RUN conda activate ml4t
run docker image build --tag jupyter/base-notebook:my_version .

I'd recommend to just install the packages you'll actually use given the notebooks of interest. Installation without pinned versions allows access to the latest versions but may fail due to conflicts given python version etc.
