I get these errors on my system, when I pass the csv generated to recommendations infra script

Placed the csv in ./recommendations_demo/local/ folder

./recommendations_demo.sh -c openshift -o quay.io/kruize/autotune_operator:0.3 --dataDrivenRecommendations --dataDir="./recommendations_demo/local/" --mode=crc

Running the recommendation Infra demo with the existing data in crc mode...
Inserting the results in kruize from :  ./recommendations_demo/local/
