pandas problem (at first run), python-tk missing (2nd run)

problem: pandas (1st run), python-tk (2nd run)

• What did you expect to happen?
  that the tutorial runs fine

  catalyst run -f buy_and_hodl.py --start 2015-3-1 --end 2017-6-28 --capital-base 100000 -o bah.pickle

• What happened instead?
  it stops with this error:

  File ".../enigmampc/catalyst/catalyst-venv/local/lib/python2.7/site-packages/catalyst/data/loader.py", line 367, in ensure_crypto_benchmark_data
    if not has_data_for_dates(daily_close, first_date, last_date):
  File ".../enigmampc/catalyst/catalyst-venv/local/lib/python2.7/site-packages/catalyst/data/loader.py", line 97, in has_data_for_dates
    return (first <= first_date) and (last >= last_date)
  File "pandas/tslib.pyx", line 1106, in pandas.tslib._Timestamp.__richcmp__ (pandas/tslib.c:20503)
  File "pandas/tslib.pyx", line 1167, in pandas.tslib._Timestamp._assert_tzawareness_compat (pandas/tslib.c:21519)

then when I re-run it, with this error

  File ".../enigmampc/catalyst/catalyst-venv/local/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in <module>
    raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package

which I could fix with

sudo apt install python-tk

... and then ... it worked, and showed the diagrams.

What I had done before:

mkdir enigmampc
cd enigmampc
git clone https://github.com/enigmampc/catalyst.git
cd catalyst

virtualenv catalyst-venv
source ./catalyst-venv/bin/activate

pip install enigma-catalyst matplotlib

catalyst ingest
cd catalyst/examples/
catalyst run -f buy_and_hodl.py --start 2015-3-1 --end 2017-6-28 --capital-base 100000 -o bah.pickle

my system looks like this

uname --all

Yes, this is very helpful, thanks for reporting. I will take a closer look. Glad that you figured it out!

@drandreaskrueger thanks for reporting this. The first part of this issue is a duplicate of #18, which was addressed in commit 13d405b, which in turn is part of 0.1.dev7 release: 20a98a3 in the master branch. A newer version has been released since then, and we are on 0.1.dev8. New installs don't cause this issue.

The second issue has been documented in our wiki in the Troubleshooting section of Getting Started with running an algo.

Thank you.

Thanks a lot!
