Deleted:deeptools bamCoverage error

Question

[checkyodna]

I am encountering a problem when trying to use deeptools (version 2.5.4) and I cannot find any help online. My aim is to convert a BAM file to a bigWig file to visualise tracks on UCSC genome browser. I am using the following command:

bamCoverage -b Striatum_W2_UCSCindex.bam -o Striatum_W2.bw --normalizeUsing RPKM

The error I am getting might be related to my python path (I have blindly attempted a few commands as I am new to bioinformatics) and the full error message is here;

Traceback (most recent call last):
  File "/usr/local/bin/bamCoverage", line 4, in <module>
    from deeptools.bamCoverage import main

Any help would be greatly appreciated.
