trouble importing

[ghost]

Hi, I'm having some trouble importing pytides, running Python 3.6.0 on 64 bit Anaconda.
Anyone else run into this?

>>> import pytides
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\ProgramData\Anaconda3\lib\site-packages\pytides\__init__.py", line 1,
 in <module>
    import tide
ModuleNotFoundError: No module named 'tide'

I'm facing this issue too, vchkan. Did you solve it?

Hi vic, got it working with Anaconda Python 2.7.

Hi Vic,
Looks like the code is made for Python 2.(7).

• The relative import does not work in python 3.6 (e.g. "import nodal_corrections" as nc should be "from pytides import nodal_corrections as nc" in constituent.py).
• Also "reduce" is not used in Python 3, and should then be replaced by functools.reduce(), however for loop is more readible.

Nice! With these corrections should pytide start working? Em segunda-feira, 14 de agosto de 2017, Jonne Kleijer < [email protected]> escreveu:

There are several Python 3 forks:

• https://github.com/drf5n/pytides/tree/py3_v2
• https://github.com/titoconte/pytides
• and a few other forks: https://github.com/titoconte/pytides/network

I installed a different fork of pytides and it worked:
