If you’d like to download your Coursera Labs files locally:
- Each Coursera Lab experience will vary based on the course content needs and configuration, so please follow any instructions that your instructors provide to download Lab files locally.
- If you are using Jupyter Notebooks: You can follow the instructions in this article to download your Jupyter Notebook files.
If you’d like to refresh your Lab Workspace to the original files:
- If you are using Jupyter Notebooks: Please follow the “Refresh Your notebook” instructions in this article.
- Each Lab experience will vary based on the course content needs and configuration, so please follow any instructions that your instructors provide to enable file refresh. As a general rule of thumb you can also try the following steps if they are not explicitly stated otherwise in course instructions:
- Rename and save your existing file that you’d like to get a fresh copy of
- In your home Lab workspace, add “?forceRefresh=true” to the end of your Lab URL
- Reload the screen
- You should see both your old and new files in the Learner Workspace after refresh
- Your Lab item should now launch to the fresh lab file
If you are having trouble launching into your Lab experience, or receive 404 or “not found errors”:
- Have you changed any of your assessment filenames?
- Renaming your files can cause your Lab environment to error upon launch, as the launcher cannot find the expected file. You can fix this by modifying the name of your file back to the original filename and relaunching your Lab workspace.
- If you have renamed your assignment file and cannot remember the original name of the assignment, please use the steps outlined in the “If you’d like to refresh your Lab Workspace to the original files” section of this article.
- Have you changed your Lab file structure?
- When working on an assignment that uses Labs, we strongly recommend that you do not alter the file structure of your home Learner Workspace, unless your course instructor has indicated that you should do so.
- Additionally, we also recommend that you do not delete any original files in your home Learner Workspace. Deleting files or altering the file structure in your home Learner Workspace may impact your ability to submit your Lab assignment(s) appropriately.
If your Lab assessments are running slowly or freezing one you are in the Lab experience:
- For Labs that are running slowly: Try closing all assessment files that are running in your workspace and only keep the current Lab assessment file you need open. Note: If the course you are taking is in the data science domain, it is common for certain processes to take longer than others, so please do keep this in mind.
- If your Lab environment is freezing: Check your lab file size within your browser to see how big it is. All Lab files should be under 10MB. If you have added code which brings these files above 10MB, they will become read-only, which means you won’t be able to edit them anymore. If this occurs, we recommend that you save a copy of your work locally and use the steps outlined in the “If you’d like to refresh your Lab Workspace to the original files” section of this article to receive a fresh copy of your Lab file.
If certain parts of the Lab are erroring out after your code is run:
- Do you see any https or download errors provided within your Lab? If so, please note that Labs do now allow open internet access, aside from preconfigured sites that instructors have identified. Attempting to download or install any external resources outside of the preconfigured learning experience will likely result in an expected error.
If you are unable to submit your Graded Lab from your Lab workspace:
- Please check that your filename matches the original filename provided for the Lab.
- Please check to see if you’ve deleted or moved any of your Lab files and restore your files if so.
- Do you have any files in your Labs workspace that you’ve copied and now have duplicates of? If so, please either migrate your work to a single file in your Lab or save a local copy of your work. Duplicate files can interfere with submission flows, so you’ll want to delete the old duplicate file.
- If you do not recall what your prior filename or structure looked like, you can use the steps outlined in the “If you’d like to refresh your Lab Workspace to the original files” section of this article to get a fresh copy of your Lab files.
