The Fovus Python CLI
Project description
Getting Started with Fovus CLI
The official CLI tool for interacting with the Fovus Serverless HPC SaaS. Installation, setup, and usage documentation is provided here. Further detail is available via the CLI --help
command or at our CLI documentation website.
Features include job creation (with validation), job status checking, and job file downloading. In addition, reusable job and user configurations with optional command-line overriding are supported. Additional features are detailed in this README and in our help documentation (linked above).
Installation
Prerequisites
- Python and pip installation: https://www.python.org/downloads/
- Click the "Download Python" button.
- Select ALL of the following according to your operating system:
- Windows
- Install pip (should be selected by default).
- Add Python to PATH.
- Add Python to environment variables (this is generally found under "Customize Installation" and should be automatically enabled if you selected "Add Python to PATH").
- Unix-based OS
- Install or upgrade pip (under Customize)
- Shell profile updater (under Customize)
- Windows
- Close and reopen your Command Prompt/PowerShell (Windows) or terminal (Unix-based systems).
- Install fovus using pip with the following command:
pip install fovus
Note:
-
The pip package is usually bundled with Python. If you have Python and you don't have pip, you can install pip at the following link: https://pip.pypa.io/en/stable/installation/.
-
Windows: If you encounter a command not found error and have already installed Python, try re-running the Python installer, selecting "Modify". In the following menus (you may have to click "Next"), select the following options:
- Install pip (should be selected by default).
- Add Python to environment variables.
-
Unix-based OS: If you encounter any Python-related issues, try reinstalling Python according to the instructions above.
Initial setup
Before use, set up the following:
- Make sure you have an account with https://www.fovus.co
- Authenticate your account through the Fovus CLI
Authentication
To login with your Fovus credentials, run the command:
fovus --login
To logout from the Fovus CLI, run the command:
fovus --logout
To view the current user and workspace information or verify whether a user is authenticated, run the command:
fovus --user
Windows - Python can't find script
-
In "Run" (Windows + R), enter
sysdm.cpl
-
System Properties will open up. Go to Advanced -> Environment Variables
-
Under "User variables for xxx", click the variable labeled "Path"
-
Click the "Edit" button under the "User variables for xxx" section

Click the "New" button in the "Edit environment variables" pane that opens
-
In the terminal you used to install the Fovus CLI, run the following command:
pip show fovus
(this will show a message similar to the sample output provided after these instructions) -
Copy the "Location" value from the output of the above command (e.g.,
C:\Users\TestFovusUser\AppData\Local\Programs\Python\Python311\Lib\site-packages
) and paste it as a new environment variable. Once it is pasted, replace the\Lib\site-packages
with\Scripts
(e.g.,C:\Users\TestFovusUser\AppData\Local\Programs\Python\Python311\Scripts
) -
Click "OK" on all open environment variable windows.
Sample output for pip show fovus
(reference from step 6 above):
PS C:\Users\TestFovusUser> pip show fovus

Basic usage
See the "Advanced Usage" section for additional options regarding file inclusion/exclusion for create job and download job files.
Viewing your config files
fovus --open-config-folder
Note:
- Contains empty job and user config files for reference and copying.
Creating jobs
This command will upload files from the specified directory to Fovus and create a job.
Upon job creation:
- The following will be validated: your job configuration structure (if provided as JSON), your job configuration values against your chosen benchmarking profile, and your software configurations (if job is monolithic).
- A
.fovus
folder will be created in your local file root directory, which will contain ajob_data.json
file (i.e.,/path/to/job/file/root/directory/.fovus/job_data.json
. This json is used to facilitate checking job status and downloading job files by tracking the job'sjobID
.
fovus --create-job --job-config-file-path "/path/to/job/config/file.json" --job-file-root-directory "/path/to/job/file/root/directory"
Note:
- To create your own job template, do the following:
- Open the fovus config folder with
--open-config-folder
. - Make a copy of either
~/.fovus/job_configs/FOVUS_job_template_containerized.json
or~/.fovus/job_configs FOVUS_job_template_monolithic.json
. - IMPORTANT: rename your copy, or it will be overwritten.
- Fill in the fields.
- Open the fovus config folder with
- Each subdirectory in your job file root directory will be treated as its own task.
- Task folders must only contain the following characters (commas not included):
a-Z
,0-9
,-
,_
. In addition, task folders must not start with a hyphen-
or underscore_
.
- Task folders must only contain the following characters (commas not included):
- You can add the optional argument
--job-name "your_job_name_here"
to set a custom job name.
Getting job status
If you created the job using the Fovus CLI on the same local machine (i.e., the .fovus
folder was created in your job root directory -- see "Creating job" section for details):
fovus --get-job-current-status --job-file-root-directory "/path/to/job/file/root/directory
If you did not create the job using the Fovus CLI:
fovus --get-job-current-status --job-id "your_job_id"
Note:
- Job ID is viewable in the Web UI.
Downloading completed job files
If you created the job using the Fovus CLI on the same local machine (i.e., the .fovus
folder was created in your job root directory -- see "Creating job" section for details):
fovus --download-job-files --job-file-root-directory "/path/to/job/file/root/directory"
If you did not create the job using the Fovus CLI:
fovus --download-job-files --job-file-root-directory "/path/to/job/file/root/directory" --job-id "your_job_id"
Note:
- Only new or updated files will be downloaded (checked using file hash).
Advanced usage
Include/Exclude file patterns
When creating a job, the arguments --include-input
and --exclude-input
are available to you. These arguments are used to include/exclude filepaths for upload/download. Valid values for these arguments are alphanumeric along with the wildcards: * (matches any number of characters), ? (matches any single character).
For example:
--include-input "Car*/*" "config?/*"
includes:- All files under any directory that begins with
Car
. - All files in folders titled
configX
, whereX
is any character.
- All files under any directory that begins with
--exclude-input "Car*/*.log" "local?/*"
uploads all files except:- All
.log
filetypes within every directory that begins withCar
. - All files in any directory titled
localX
whereX
is any character.
- All
- The same logic applies for
--include-output
and--exclude-output
except those are used for downloading job files.
Usage with create job (--create-job)
--include-input
will only upload filepaths (relative to the job root directory) that match the expressions provided.--exclude-input
will upload all filepaths except those that match the expression provided.
Usage with download job files (--download-job-files)
--include-output
will only download filepaths (relative to the job root directory) that match the expressions provided.--exclude-output
will download all filepaths except those that match the expression provided.
Overriding
Any value in a job config or a user config can be overriden by providing the respective json key as an argument. Examples are given below, and more details are available in --help
.
Single-value arguments
All single-value arguments (i.e., not lists) can be overriden using a single argument and a value.
For example, the benchmarkingProfileName
in your job config, you can do so by providing the argument --benchmarkingProfileName "your_benchmarking_profile_name_here"
.
Lists of values
All lists of values can be overridden using a single argument and a list of values.
For example, if you want to override the supportedCpuArchitectures
in your job config, you can do so by providing the argument --supportedCpuArchitectures "x86_64" "arm64"
.
Lists of objects
Currently, the only list of objects that exists is the monolithicList
, which is only used for monolithic jobs. The only value that can be overridden in a monolithicList
is licenseCountPerTask
.
To do this, use the command --monolithic-override "vendor_name" "software_name" "license_feature" "your_new_license_count_here"
.
Note:
- The monolithicList object must already exist in the job config JSON.
- The vendor name, software name, and license feature are used to reference the specific object within the list and do not override existing values.
- If an object that does not match the given vendor name, software name, and license feature does not exist, an error will be thrown.
