I get the following error whenever I run `using Flux` or `using CuArrays`, but I haven’t gotten the error when running any other Julia packages so far. Honestly I have no idea what it means or what to do about it, and any help would be appreciated.

The error is as follows:

**Author:** ![John\_G](https://sea2.discourse-cdn.com/julialang/user_avatar/discourse.julialang.org/john_g/32/8483_2.png) [@John\_G](https://discourse.julialang.org/u/John_G)\

Additionally I haven’t been able to get CuArrays to work properly, and I have yet to find a Flux tutorial that I can run succesfully in its entirety. I am running my code in a conda environment on a server with a GPU without root access, and I’ve been able to run deep learning models using Pytorch and fastai without any problems in the same conda environment.

The server is running on Ubuntu 16.04.6 LTS (GNU/Linux 4.15.0-58-generic x86\_64).

This is information I get on the GPU when I run `lshw -C display` from the terminal:

I am running Julia Version 1.0.3 (conda-forge-julia release). These is the output from running `using Pkg; Pkg.installed()`:

I don’t have a ton of experience with Julia, but I am really interested in getting setup using Julia for some of my deep learning projects. As the above error messages are unintuitive to me, any help would be very much appreciated.

(Note: I split this message up into parts due to the character limit on discourse)

Consider updating Julia to at least 1.1, I had similar issues that disappeared with Julia version update.
