Hello! I'm attempting to get the dataset viewer working with my tar.gz files, but I run into the above error.

The structure of the dataset is nested tar.gz files, with each folder (i.e. conv1d) containing N tar.gz archives, each of those N archives (i.e conv1d/archive_1.tar.gz) containing M tar.gz archives, with each of those M archives containing a series of files and directories corresponding to some firmware projects for FPGAs.

I have also checked that each tar file in the conv1d directory is valid using the following script:

#!/bin/bash

# Directory containing tar.gz files
directory=${1:-.}
# Number of cores to use
num_cores=${2:-1}

# Function to check a single file
check_file() {
    file=$1
    if gunzip -c "$file" | tar -t > /dev/null 2>&1; then
        echo "Valid: $file"
    else
        echo "Invalid: $file"
    fi
}

export -f check_file

# Find all tar.gz files and process them in parallel
find "$directory" -name "*.tar.gz" -type f | parallel -j "$num_cores" check_file

Thank you for your help!
