Hi,
I've hit a bunch of different errors at once - NoSectionError, KeyError, PermissionError, and TypeError - while trying to train a LSTM-CNN model on Jupyter Notebook. The model's code is given in EEGLearn (https://github.com/pbashivan/EEGLearn). These are my configurations: Python 3.7.0 (Anaconda distribution) Theano 0.8.2 (because this is the version Lasagne recommends) - installed using pip Lasagne 0.1 - installed using pip I tried to *print(theano.config)*, but as the code between '=====' shows, it didn't work... ===== *ERROR WHEN PRINTING THEANO.CONFIG* Python 3.7.0 (default, Jun 28 2018, 08:04:48) [MSC v.1912 64 bit (AMD64)] :: Anaconda, Inc. on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import theano >>> print(theano.config) Traceback (most recent call last): File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 159, in fetch_val_for_key return theano_cfg.get(section, option) File "C:\Anaconda\envs\py36gpu\lib\configparser.py", line 780, in get d = self._unify_values(section, vars) File "C:\Anaconda\envs\py36gpu\lib\configparser.py", line 1146, in _unify_values raise NoSectionError(section) from None configparser.NoSectionError: No section: 'blas' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 317, in __get__ delete_key=delete_key) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 163, in fetch_val_for_key raise KeyError(key) KeyError: 'blas.ldflags' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\gof\cmodule.py", line 1748, in _try_compile_tmp os.remove(exe_path + ".exe") PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\Michelle\\AppData\\Local\\Temp\\try_blas_hzw0uodq.exe' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 197, in __str__ _config_print(self.__class__, sio, print_doc=print_doc) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 173, in _config_print print(" Value: ", cv.__get__(True, None), file=buf) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py", line 321, in __get__ val_str = self.default() File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configdefaults.py", line 1243, in default_blas_ldflags res = try_blas_flag(ret) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configdefaults.py", line 1300, in try_blas_flag flags=cflags, try_run=True) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\gof\cmodule.py", line 2070, in try_compile_tmp theano.config.cxx) File "C:\Anaconda\envs\py36gpu\lib\site-packages\theano\gof\cmodule.py", line 1753, in _try_compile_tmp err += "\n" + str(e) TypeError: can't concat str to bytes ===== *ERROR WHEN TRAINING LSTM-CNN MODEL ON JUPYTER NOTEBOOK* ---------------------------------------------------------------------------NoSectionError Traceback (most recent call last)C:\Anaconda\envs\py36gpu\lib\site-packages\theano\configparser.py in fetch_val_for_key(key, delete_key) 158 try:--> 159 return theano_cfg.get(section, option) 160 except ConfigParser.InterpolationError: C:\Anaconda\envs\py36gpu\lib\configparser.py in get(self, section, option, raw, vars, fallback) 779 try:--> 780 d = self._unify_values(section, vars) 781 except NoSectionError: C:\Anaconda\envs\py36gpu\lib\configparser.py in _unify_values(self, section, vars) 1145 if section != self.default_section:-> 1146 raise NoSectionError(section) from None 1147 #
