Problem loading database, please help!

[charleywan2004]

I am new in using phreeqpy. 

I just installed phreeqpy by using "pip install -U phreeqpy". I also installed "Phreeqc Interactive 3.3.3-10424".

I used the example from "http://water.usgs.gov/nrp/proj.bib/Publications/2011/muller_parkhurst_etal_2011.pdf", and encountered the following error

>>> ================================ RESTART ================================

>>> 

phreeqc.phc_database_error_count= 295

Traceback (most recent call last):

  File "C:\Users\218007366\Desktop\PhreeqcWebDEV\testPhreeqc.py", line 37, in <module>

    raise Exception(msg + self.get_error_string())

Exception: An error occured.

I saw the post "problem reading database", I put the absolute path in "phreeqc.load_database". It still showed the same error message, and phreeqc.phc_database_error_count=295. Please help!

I am not fluent in Python, but do you need two back slashes after USGS?

change:

r"C:\\Program Files (x86)\\USGS\Phreeqc Interactive
3.3.3-10424\\database\\phreeqc.dat"

either in:

r"C:\Program Files (x86)\USGS\Phreeqc Interactive 3.3.3-10424\database\phreeqc.dat"

or in:

"C:\\Program Files (x86)\\USGS\Phreeqc Interactive
3.3.3-10424\\database\\phreeqc.dat")

The prefix `r` creates a raw string and you can paste the full path from explorer.
Without the `r`, use a double backslash. But don't do both at the am time.

I tried the following 4 scenarios. (I also put "phreeqc.dat" in the current work directory for the last 2 scenarios). But I still got the same error message. Please help.  

 

phreeqc = phreeqc_mod.IPhreeqc()

#(1)

#phreeqc.load_database(r"C:\Program Files (x86)\USGS\Phreeqc Interactive 3.3.3-10424\database\phreeqc.dat")

#(2)

#phreeqc.load_database("C:\\Program Files (x86)\\USGS\\Phreeqc Interactive 3.3.3-10424\\database\\phreeqc.dat")

#(3)

#phreeqc.load_database(r"phreeqc.dat")

#(4)

phreeqc.load_database("phreeqc.dat")

I think you might be using an older phreeqc.dll that doesn't support some of the newer features in the current version of phreeqc (3.3.3).  Could you try using the wateq4f.dat database which doesn't use any of the new features.

Yes, it works. Thank you so much!

I used the database from version 2.18 and it worked.

Please let me know if phreeqpy is updated with the current version of phreeqc (3.3.3).
