AttributeError: 'module' object has no attribute 'open'

I am trying to open a .csv compressed to a .lzma file in Linux using the following code:

import lzma
import pandas as pd

myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

with lzma.open(myfile,'rt') as f:
   pair_info=pd.read_csv(f,engine='c',header=0,index_col=0)

Where myfile is a path that exists in Linux.

However I get the error:

with lzma.open(stock,'rt') as f:
AttributeError: 'module' object has no attribute 'open'

I have tried adding the following:

import lzma
import pandas as pd

    myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

    with open(myfile) as compressed:
         with lzma.LZMAFile(compressed,'r') as uncompressed:
             line in uncompressed:
             print(line)  

but I get the error:

    with lzma.LZMAFile(compressed,'r') as uncompressed:
TypeError: coercing to Unicode: need string or buffer, file found

I have also tried:

import pandas as pd
import lzma
import pickle

myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

myoutput = pickle_load(myfile,'lzma')
print(myoutput )

def pickle_load(filePath,compression=None):
    open_cmd=open if compression is None else __import__(compression).open
    with open_cmd(filePath,'r') as f:
        output=pickle.load(f)
    return output

But again I get the error:

open_cmd=open if compression is None else __import__(compression).open
AttributeError: 'module' object has no attribute 'open'

When I run python-v on the cmd line I get the output:

When I then run import lzma I get the output:

Could someone let me know what I've done wrong and how I can get this working?

I've had a look around but can't see any other solution. If anyone could offer some assistance it would be much appreciated.
