Error running artic minion

[jvelasquez24]

Hello I ran the following command
artic minion --normalise 200 --threads 4 --scheme-directory ~/artic-ncov2019/primer_schemes --read-file artic.fastq --fast5-directory fast5_pass/ --sequencing-summary sequencing_summary.txt ncov2019/V4 artic_sample

and I get the following errors.
I am not sure what would solve this issue.
