[Python] error: no such module: fts4; using - fuzzymatcher package with anaconda jupyter...

I'm using jupyter notebook and trying to run this code:

import json
import time
import fuzzymatcher

start_time = time.time()

df = data.parse (sheet_name=0)
inKey = list()
for idx,sd in enumerate(df['Structure']):
print(idx)
F = open ("temp.sdf","w")
F.writelines (sd)
F.close()

inKey = pd.DataFrame(inKey)
inKey.columns = ['InChIKey']
CD = pd.concat([df, inKey], axis=1, sort=False)


print("--- %s seconds --f-add 3 cols" % (time.time() - start_time))

df_excel = CD
# Merge by inchikey
joindata_by_inchikey = pd.merge(left=df_excel, right=df_hmdb, how='inner', left_on='InChIKey', right_on='inchikey')

joindata_by_name = joindata_by_name[joindata_by_name['best_match_score'] > 0.55]
# Drop columns the
joindata_by_name.drop(['best_match_score', '__id_left', '__id_right'], axis=1, inplace=True)
print("--- %s seconds --f-merge by name" % (time.time() - start_time))

print("--- %s seconds --f-merge by CF" % (time.time() - start_time))



(I'm not sure the code is relevant since I load files that are not shared in quesion)

This is the error I get:

OperationalError: no such module: fts4


The line with error of fuzzymatcher used to work using Pycharme on different computer but on jupyter notebook it does not.

I checked this for answers :

1. perationalError: No Such Module:fts4
2. OperationalError: no such module: fts4

But no use and I do not understand what to do

any help idea hint thoughts are fappreciated
