Error in st.cal_qc

[tianchen2019]

my code is :
import stream as st
adata=st.read(file_name='/outs/filtered_peak_bc_matrix/matrix.mtx',
file_sample='/outs/filtered_peak_bc_matrix/barcodes.tsv',
file_feature='/outs/filtered_peak_bc_matrix/peaks.bed',
file_format='mtx',workdir='./result_atac')
adata.var.index =adata.var[0].astype(str) + '' + adata.var[1].astype(str) +'' + adata.var[2].astype(str)
st.cal_qc(adata2,assay='atac')
the error is :
