Problem importing dolo " 'charmap' codec can't decode byt"

marcdelabarrera commented 3 years ago

I have installed dolo (0.4.9.14) on a Windows but when I import dolo, the following error arises:

~\anaconda3\lib\encodings\cp1252.py in decode(self, input, final)
     21 class IncrementalDecoder(codecs.IncrementalDecoder):
     22     def decode(self, input, final=False):
---> 23         return codecs.charmap_decode(input,self.errors,decoding_table)[0]
     24 
     25 class StreamWriter(Codec,codecs.StreamWriter):

UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 1179: character maps to <undefined>

Any idea why this might be happening?

hmm, can you tell me more about your conda environment ? most importantly the python version ?

Thank you for quick reply Pablo. I am using anaconda on a windows, with Pyhon 3.7.6. I don't want to get back to Dynare!

Also, I tried to install it on Google Colab, I could import it, but when I try to run your first example

model = yaml_import("https://raw.githubusercontent.com/EconForge/dolo/master/examples/models/rbc.yaml")

I get the error

/usr/local/lib/python3.6/dist-packages/dolo/linter.py in check_definitions(data)
    275 
    276     new_definitions = dict()
--> 277     for k, v in definitions.items():
    278         pos = definitions.lc.data[k]
    279         if k in known_symbols:

AttributeError: 'LiteralScalarString' object has no attribute 'items'

Hi @marcdelabarrera, There are two different issues here:

Google Colab is using python 3.6, and dolo requires python >=3.7 . We have dropped compatibility a while ago, and unless there is a big demand for it (like a class using it for teaching), there are no plans to go back
- there are other options to use dolo without any installation: mybinder and gitpod are two of them. We should add it to the documentation.
As for the error in the first message, if you can still replicate it, would you mind pasting the full traceback ? I would suppose one file, is incorrectly decoded under windows, and it would help to know which one.

Hi, i installed dolo (dolo-0.4.9.14.dist-info) but didn't succed to import it [i use python 3.7.4 64-bit (conda) using VS-Code with Jupyter extention] here is my log:

I'm using windows, changing line 29 in grammar.py to:

grammar_0 = open(DATA_PATH, "rt", encoding='utf-8').read()

solves the problem as now the encoding is specified, otherwise it seems windows is confused.

Can submit a PR if needed

Thank you! I thought this bug had been fixed, (and grammar.py moved to dolang.py : https://github.com/EconForge/dolang.py/blob/master/dolang/grammar.py) Maybe I need to do a new release.
