Error installing ImageView Library

New to Julia
1

I work in medical imaging and am therefore trying to install the ImageView Library, but I am getting an error when I build it, as follows (sorry this is a bit lengthy but I have no idea what is important and what is not). Does anyone know how to fix this issue? thanks

I also have this error:

What happens when you try to install something from the terminal, e.g. sudo apt-get install libgtk-3-dev?

Also, please quote your code: Please read: make it easier to help you

Oh, sorry, I have added a screenshot of my code. I have tried running that command from the terminal, it installed something (I assume libgtk-3-dev) but I still get the exact same error.

Hello @samantp at the moment I work with a company which is applying Machine Learning to mammography. Interesting stuff… but a Python shop!
May I ask what work you are doing in medical imaging?
Also are you running Julia in some sort of VM?

6

I think this is the clue - which is why I ask you about the setup you have. How are you logging in?
With Julia 1.0.3 on Ubuntu 18.04 I am able to add the ImageView package - actually it is still building.
This is on my own laptop though, no VM or Docker image

7

I am trying to use Machine learning in analysing MR linac images. I am running Julia 1.04 via Jupyter notebook in Ubuntu 18.04. I have tried building the package just by launching julia through my ubuntu terminal but I get the same error message unfortunately.

8

Plese try thse commands at the REPL
julia> run(date)

julia> run(sudo date)

Also in my ignoramce… I know what an MRI scanner is… and what a Linac is…
What the heck is an MR Linac?

9

Also at your terminal prompt just:
sudo date

You may be interested to know that I worked in conformational radiotherapy a looooooonnnnggg time ago.
Programming in Fortran on a Sun workstation with 2 Mbytes - yes Mbytes- of RAM.
A simple 2D program was difficult to run. I Was trying to use simulated annealing.

10

If you can use Julia 1.3 the installation mechanism is completely different and should not require sudo.

11

Just the sum of its components :slight_smile: it’s a Linac with an integrated MR scanner: MR-LINAC image-guided radiotherapy

Unfortunately both commands return errors:
julia> run(date)
ERROR: UndefVarError: date not defined
Stacktrace:
[1] top-level scope at none:0

julia> run(sudo date)
ERROR: syntax: missing comma or ) in argument list

12

Ooof, sounds rough! How the times have changed :slight_smile:

13

You need to use ` to create a runnable command:

julia> run(date)
ERROR: UndefVarError: date not defined
Stacktrace:
 [1] top-level scope at REPL[51]:1

julia> run(`date`)
Fr Jän 31 11:59:01 CET 2020
Process(`date`, ProcessExited(0))

I believe I have found a solution for this issue, the version of Julia I was using was 1.0.3, I have uninstalled this and instead started on 1.3.1 and ImageView works without issue. I think that ImageView is not compatible with older versions of Julia. Thanks to all responses who tried to help! I guess I should have mentioned the Julia version, apologies!

15

Glad it works now.

For most non-mac people ImageView works fine on Julia 1.0.x. As I said above (Error installing ImageView Library - #10 by tim.holy), prior to Julia 1.3 it does require sudo, and that seemed to be where you were having trouble.
