+
+**Parameters**
+
+**name** (`str`, *optional*, defaults to **None**): a string that indicates the alias of a specified logger.
+
+**Example:**

+
+**Example:**
+
+```python

+set_verbosity(INFO)
+```
+
+**set_verbosity_info**
+
+`set_verbosity_info()`: sets the level of the root logger to **INFO**.
+
+**Example:**
+
+```python
+from openmind_hub import set_verbosity_info
+        
+set_verbosity_info()
+```
+
+**set_verbosity_warning**
+
+`set_verbosity_warning()`: sets the level of the root logger to **WARNING**.

+
+set_verbosity_warning()
+```
+
+**set_verbosity_debug**
+
+`set_verbosity_debug()`: sets the level of the root logger to **DEBUG**.
+
+**Example:**

+```
+
+**set_verbosity_error**
+
+`set_verbosity_error()`: sets the level of the root logger to **ERROR**.
+
+**Example:**
+
+```python

+        
+set_verbosity_error()
+```
+
+## openmind_hub.replace_invalid_characters
+
+**Description**
+
+Filters input character strings by blocklist to prevent risks in logs, and returns the filtered character strings. The filtering rules are as follows:
+
+1. The following characters are removed: [
+        "\r",
+        "\n",
+        "\t",
+        "\f",
+        "\v",
+        "\b",
+        "\u000A",
+        "\u000D",
+        "\u000C",
+        "\u000B",
+        "\u0008",
+        "\u007F",
+        "\u0009"
+    ]
+2. Each time four consecutive spaces are identified, they are replaced with one space.
+
+**Parameters**
+
+**content** (`str`, *required*): character string to be filtered.
+**allow_line_separator** (`bool`, *optional*, defaults to `False`): whether the newline (`\n`) is allowed in log information.
+
+**Prototype**

 # Uploading Files

+[Access tokens](../quick_start.md#access-token) are required to upload files to a repository.
 
 The openMind Hub Client controls file upload paths through blocklist and trustlist. The absolute path of a file cannot start with a path in the blocklist (except the default cache path `~/.cache/openmind`) and must be in the trustlist. The blacklist includes `["/etc", "/var", "/bin", "/boot", "/lib", "~/."]`. The default trustlist is `["/tmp", "~/"]` in Linux and `["~/", "D:", "E:", "F:"]` in Windows. You can configure the environment variable `HUB_WHITE_LIST_PATHS` (separate each path by commas) to configure the trustlist. In addition, the priority of the blocklist permission is higher than that of the trustlist permission.
