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

[marcdelabarrera]

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.
