Python (version-specific) syntax error?

[Mike Weigand]

I'm a new user attempting to install v4 on Ubuntu 14.04. When running "anvi-self-test --suite mini" I encounter the following error, which also reproduces with "anvi-run-hmms --help":

Traceback (most recent call last):

  File "/usr/local/bin/anvi-run-hmms", line 17, in <module>

    from anvio.tables.hmmhits import TablesForHMMHits

  File "/usr/local/lib/python3.4/dist-packages/anvio/tables/hmmhits.py", line 15, in <module>

    from anvio.drivers.hmmer import HMMer

  File "/usr/local/lib/python3.4/dist-packages/anvio/drivers/hmmer.py", line 110

    '-o', self.hmm_scan_output, *noise_cutoff_terms.split(),

                                                   ^

SyntaxError: can use starred expression only as assignment target

Perhaps this is due to my using python3.4? I'm admittedly not a frequent python user. 

Thanks

Hi Mike,

I'm afraid that that syntax is not known to Python 3.4 error, and was introduced in Python 3.5 :(

Is using Python >= 3.5 an option for you?

Best,

Yeeeeeeeep. Took some trickeration, and a lot of swearing (at Ubuntu), but I got this running. I might suggest revision to the install instructions, which suggest any flavor of 'Python 3' will work.

Thanks.

There are (at least) two distinguishable kinds of errors: syntax errors and ... ZeroDivisionError: division by zero >>> 4 + spam*3 Traceback (most recent .... that to create specific exception classes for different error conditions:.
