schrodinger.utils.env module¶
-
schrodinger.utils.env.
append_path
(env_dict, env_var, path)¶ Appends a path to env_var (defined as constants in schrodinger.utils.env) in the env_dict. This uses the traditional path seperator. We normalize the path argument.
Parameters: - env_var (str) – existing environment variable (example: schrodinger.utils.env.PATH)
- path (str) – path to extend with
-
schrodinger.utils.env.
prepend_path
(env_dict, env_var, path)¶ Appends a path to env_var (defined as constants in schrodinger.utils.env) We normalize the path argument.
Parameters: - env_var (str) – existing environment variable (example: schrodinger.utils.env.PATH)
- path (str) – path to extend with
-
schrodinger.utils.env.
swap_ld_library_path
()¶ Restore LD_LIBRARY_PATH to the value that it was when we first ran a toplevel script. ORIGINAL_LD_LIBRARY_PATH is set by toplevel.sh

class
schrodinger.utils.env.
EnvironmentContext
(key, value)¶ Bases:
object
Context manager to temporarily set an environment variable and then return it to its original value upon exit.
-
__init__
(key, value)¶ Initialize self. See help(type(self)) for accurate signature.

class
schrodinger.utils.env.
remove_ssl_ld_library_path
¶ Bases:
contextlib.ContextDecorator
Temporarily remove SSL library path from the LD_LIBRARY_PATH. This will force ssh, as called by MPI, to be linked against the system libcrypto rather than the one in the Schrodinger software (JOBCON-5027). But sometimes the user has ssh but not libcrypto and then their ssh has to use our libcrypto (DESMOND-7780). So test whether ssh fails or not by actually running it. What a world!

__init__
¶ Initialize self. See help(type(self)) for accurate signature.

-
schrodinger.utils.env.
prepend_sys_path
(path)¶ Prepend to a specific path to sys.path. Strongly consider using a namespace
Parameters: path (str) – directory name of path
-
schrodinger.utils.env.
add_cuda_stubs_for_tensorflow
(env_dict)¶ Prepends the CUDA stubs library to LD_LIBRARY_PATH if libcuda.so is not linked to the tensorflow library.
Parameters: env_dict (dict) – dict of the environment
-
schrodinger.utils.env.
find_knime_java_path
()¶ Find the path to the jre included with KNIME
Raises: RuntimeError – if KNIME is not installed or it cannot find java Returns: the path to the java file in the jre Return type: str
