"genome" was provided but still raise an error

[limin321]

Hi,

I want to extract a cDNA sequence by running the following code:

print(transcript.Transcript('MYO6-204','6',75749239,75919537,'+','protein_coding','ENSG00000196586','GRCh38'))

However, it raised some error showed as below

"

"

I thought "'GRCh38'" will specify which genome to research, why still have this issue?

Can anyone help what might go wrong with my code?

Thanks in advance.

Best,
LC
