Hi,  
When building the docker image, I get the following error. Basically, it says the “cartopy” package needs “numpy” installed, but it get installed right before.

Hi @sjinko - are you installing numpy and cartopy in the same `pip install` statement?

This happens when I start a new environment on Renkulab, and the packages are getting installed as part of the requirements.txt file. I do not specify installing “cartopy”, so I think it’s a dependency from another package, I can’t figure out which one.

I get to build the Docker image if I remove everything from the requirements.txt file, but then, the create a new environment stalls on  
`Verifying available environments... `  
I also get this notification on top:  
`An error prevented checking integration of the project with the Knowledge Graph. Error: "Error 500"`

Yes, apologies for that we are in the middle of an outage - you can follow updates on [renkulab.statuspage.io](http://renkulab.statuspage.io)

As far as your cartopy problem goes - this is due to the fact that cartopy doesn’t specify their _install_ dependencies properly. They require numpy when the package is being installed, meaning that if numpy is installed at the same time as cartopy, _it is not installed yet_ and cartopy’s `setup.py` doesn’t see it. Try adding a line just above that installs just numpy, e.g.

```auto
RUN pip install numpy

```

I added `RUN pip install numpy` to the _requirements.txt_ file, but I get this:

` ERROR: Invalid requirement: 'RUN pip install numpy' (from line 1 of /tmp/requirements.txt) 43 The command '/bin/sh -c conda env update -q -f /tmp/environment.yml && /opt/conda/bin/pip install -r /tmp/requirements.txt && conda clean -y --all && conda env export -n "root"' returned a non-zero code: 1 47 ERROR: Job failed: exit code 1`

Even if I remove everything from the _requirements.txt_ file, the “start a new interactive environment” gets stuck on: `Loading environment parameters...`

Ah sorry, I should have been more clear - you need to add that line to the `Dockerfile` just before the `RUN pip install -r /tmp/requirements.txt` line.

It does the trick. I get to build the Docker image, but then, it still gets stuck on `Loading environment parameters...`

Yes, the outage is still on-going – see [5/19/20 renkulab.io outage](https://renku.discourse.group/t/5-19-20-renkulab-io-outage/124)

Hi @sjinko [renkulab.io](http://renkulab.io) is back to (hopefully) normal - let me know if the image build worked as expected!

Ok, I didn’t get the outage had this effect. Thanks for the help. As usual, @rrrrrok, you save the day!
