How to Zip Files in Mac or Linux Using Tar for AWS SageMaker

Learn how to zip files in Mac or Linux using tar for AWS SageMaker, what are the possible causes of errors, and how to fix them.

AWS SageMaker is a service that allows you to build, train, and deploy machine learning models in the cloud. To use SageMaker, you need to upload your model files in a compressed format, such as tar.gz. However, you may encounter some issues when zipping files in different operating systems, such as Mac and Linux. In this article, we will explain how to zip files in Mac or Linux using tar for AWS SageMaker, what are the possible causes of errors, and how to fix them.

How to Zip Files in Mac or Linux Using Tar

To zip files in Mac or Linux using tar, you can use the following command:

tar -czvf model.tar.gz model

This command will create a file named model.tar.gz, which contains the model folder and its contents. The model folder should have the following structure:

model/            
    |- model.pth             
    |- code/                     
         |- inference.py                    
         |- requirements.txt

The model.pth file is the trained model weights, and the code folder contains the inference.py script and the requirements.txt file, which specify the dependencies for the model. This folder structure is required by AWS SageMaker, as described in the documentation.

Possible Causes of Errors When Zipping Files in Mac or Linux

If you zip files in Mac and upload them to AWS SageMaker, you may encounter some errors, such as:

• ClientError: No module named ‘model’
• ClientError: No such file or directory: ‘model.pth’
• ClientError: No such file or directory: ‘code/inference.py’

These errors indicate that AWS SageMaker cannot find the model files or the code files in the expected locations. One possible cause of these errors is that Mac uses a different file system than Linux, and therefore, the tar command may create a different archive structure. For example, Mac may add some hidden files or folders, such as ._model or __MACOSX, which may interfere with the expected structure. Another possible cause is that Mac may use a different compression algorithm than Linux, and therefore, the tar command may create a different archive format. For example, Mac may use gzip or bzip2, while Linux may use xz or lzma.

How to Fix Errors When Zipping Files in Mac or Linux

To fix the errors when zipping files in Mac vs Linux, you can try the following solutions:

Solution 1: Use the same operating system as the target platform

If you are using AWS SageMaker, it is recommended to use Linux, as it is the default operating system for the SageMaker instances. You can use a virtual machine, a docker container, or a cloud service to run Linux on your Mac.

Solution 2: Use the same compression algorithm as the target platform

If you are using AWS SageMaker, it is recommended to use gzip, as it is the default compression algorithm for the tar command. You can specify the compression algorithm by using the -z option for gzip, the -j option for bzip2, the -J option for xz, or the -a option for lzma.

Solution 3: Exclude any hidden files or folders from the archive

You can use the –exclude option to specify the files or folders that you want to exclude from the archive. For example, you can use the following command to exclude the ._model and __MACOSX files or folders:

tar -czvf model.tar.gz --exclude '._*' --exclude '__MACOSX' model

Frequently Asked Questions (FAQs)

Question: How can I check the structure and the format of the tar.gz file?

Answer: You can use the tar -tvf model.tar.gz command to list the contents of the archive and see the structure. You can use the file model.tar.gz command to see the format of the archive and the compression algorithm.

Question: How can I unzip the tar.gz file?

Answer: You can use the tar -xzvf model.tar.gz command to extract the contents of the archive to the current directory.

Question: How can I zip multiple files or folders in one command?

Answer: You can specify multiple files or folders as arguments to the tar command. For example, you can use the following command to zip the model folder and the data folder in one archive:

tar -czvf model_data.tar.gz model data
