python - How to install psycopg2 for use in HDInsight PySpark Jupyter notebook -


i need "import psycopg2" part of pyspark script.

per documentation:

!pip install psycopg2

but results in syntax error (as ! command does).

i able install in ssh session /usr/bin/anaconda/bin/python, appears jupyter may using different different environment?

i tried forcing

os.environ["pythonpath"]

in notebook no luck, mean cell in notebook:

  • import psycopg2 results in error module can't found
  • help("modules") not show psycopg2
  • help("modules psycopg2") results in following error:
here list of matching modules.  enter module name more help.  failed write user configuration file. please submit bug report. sqlalchemy.dialects.postgresql.psycopg2 - .. dialect:: postgresql+psycopg2 sqlalchemy.dialects.postgresql.psycopg2cffi - .. dialect:: postgresql+psycopg2cffi

did make typo? text 'pyscopg2' not 'psycopg2'

!pip install psycopg2

for python 3.5 , python 2.7 installed on azure notebooks.
